+---+Falcon Data Import and Export
+
+
+---++Overview
+
+Falcon provides constructs to periodically bring raw data from external data sources (like databases, drop boxes etc)
+onto Hadoop and push derived data computed on Hadoop onto external data sources.
+
+As of this release, Falcon only supports Relational Databases (e.g. Oracle, MySQL etc) via JDBC as external data source.
+The future releases will add support for other external data sources.
+
+
+---++Prerequisites
+
+Following are the prerequisites to import external data from and export to databases.
+
+   * *Sqoop 1.4.6+*
+   * *Oozie 4.2.0+*
+   * *Appropriate database connector*
+
+
+*Note:* Falcon uses Sqoop for import/export operation. Sqoop will require appropriate database driver to connect to
+the relational database. Please refer to the Sqoop documentation for any Sqoop related question. Please make sure
+the database driver jar is copied into oozie share lib for Sqoop.
+
+<verbatim>
+For example, in order to import and export with MySQL, please make sure the latest MySQL connector
+*mysql-connector-java-5.1.31.jar+* is copied into oozie's Sqoop share lib
+
+/user/oozie/share/lib/{lib-dir}/sqoop/mysql-connector-java-5.1.31.jar+
+
+where {lib-dir} value varies in oozie deployments.
+
+</verbatim>
+
+---++ Usage
+---+++ Entity Definition and Setup
+   * *Datasource Entity*
+      Datasource entity abstracts connection and credential details to external data sources. The Datasource entity
+      supports read and write interfaces with specific credentials. The default credential will be used if the read
+      or write interface does not have its own credentials. In general, the Datasource entity will be defined by
+      system administrator. Please refer to datasource XSD for more details.
+
+      The following example defines a Datasource entity for a MySQL database. The import operation will use
+      the read interface with url "jdbc:mysql://dbhost/test", user name "import_usr" and password text "sqoop".
+      Where as, the export operation will use the write interface with url "jdbc:mysql://dbhost/test" with user
+      name "export_usr" and password specified in a HDFS file at the location "/user/ambari-qa/password-store/password_write_user".
+
+      The default credential specifies the password using password text and will be used if either read or write interface
+      does not provide credentials.
+
+      The available read and write interfaces enable database administrators to segregate read and write workloads.
+
+      <verbatim>
+
+      File: mysql-database.xml
+
+      <?xml version="1.0" encoding="UTF-8"?>
+      <datasource colo="west-coast" description="MySQL database on west coast" type="mysql" name="mysql-db" xmlns="uri:falcon:datasource:0.1">

+      </datasource>
+      </verbatim>
+
+   * *Feed  Entity*
+      Feed entity now enables users to define IMPORT and EXPORT policies in addition to RETENTION and REPLICATION.
+      The IMPORT and EXPORT policies will refer to a already defined Datasource entity for connection and credential
+      details and take a table name from the policy to operate on. Please refer to feed entity XSD for details.
+
+      The following example defines a Feed entity with IMPORT and EXPORT policies. Both the IMPORT and EXPORT operations
+      refer to a datasource entity "mysql-db". The IMPORT operation will use the read interface and credentials while
+      the EXPORT operation will use the write interface and credentials. A feed instance is created every 1 hour
+      since the frequency of the Feed is hour(1) and the Feed instances are deleted after 90 days because of the
+      retention policy.
+
+
+      <verbatim>

+
+   * *Import policy*
+     The import policy uses the datasource entity specified in the "source" to connect to the database. The tableName
+     specified should exist in the source datasource.
+
+     Extraction type specifies whether to pull data from external datasource "full" everytime or "incrementally".
+     The mergepolicy specifies how to organize (snapshot or append, i.e time series partiitons) the data on hadoop. 
+     The valid combinations are: 
+      * [full,snapshot] - data is extracted in full and dumped into the feed instance location.
+      * [incremental, append] - data is extracted incrementally using the key specified in the *deltacolumn* 
+        and added as a partition to the feed instance location. 
+      * [incremental, snapshot] - data is extracted incrementally and merged with already existing data on hadoop to
+        produce one latest feed instance.*This feature is not supported currently*. The use case for this feature is 
+        to efficiently import very large dimention tables that have updates and inserts onto hadoop and make it available
+        as a snapshot with latest updates to consumers.
+
+      The following example defines an incremental extraction with append organization:
+
+      <verbatim>
+           <import> 
+                <source name="mysql-db" tableName="simple">
+                    <extract type="incremental">
+                        <deltacolumn>modified_time</deltacolumn>
+                        <mergepolicy>append</mergepolicy>
+                    </extract>  
+                    <fields>
+                        <includes>
+                            <field>id</field>
+                            <field>name</field>
+                        </includes>
+                    </fields>
+                </source>
+                <arguments>
+                    <argument name="--split-by" value="id"/>
+                    <argument name="--num-mappers" value="2"/>
+                </arguments>
+            </import>
+	</verbatim>
+
+      
+     The fields option enables to control what fields get imported. By default, all fields get import. The "includes" option
+     brings only those fields specified. The "excludes" option brings all the fields other than specified.
+
+     The arguments section enables to pass in any extra arguments needed for fine control on the underlying implementation --
+     in this case, Sqoop.
+
+   * *Export policy*
+
+     The export, like import, uses the datasource for connecting to the database. Load type specifies whether to insert
+     or only update data onto the external table. Fields option behaves the same way as in import policy.
+     The tableName specified should exist in the external datasource.
+
+---+++ Operation
+   Once the Datasource and Feed entity with import and export policies are defined, Users can submit and schedule
+   the Import and Export operations via CLI and REST API as below:
+
+   <verbatim>
+
+    ## submit the mysql-db datasource defined in the file mysql_datasource.xml
+    falcon entity -submit -type datasource -file mysql_datasource.xml
+
+    ## submit the customer_feed specified in the customer_email_feed.xml
+    falcon entity -submit -type feed -file customer_email_feed.xml
+
+    ## schedule the customer_feed
+    falcon entity -schedule -type feed -name customer_feed
+
+   </verbatim>
+
+   Falcon will create corresponding oozie bundles with coordinator and workflow for import and export operation.

+---+Building & Installing Falcon
+
+
+---++Building Falcon
+
+---+++Prerequisites
+
+   * JDK 1.7/1.8
+   * Maven 3.2.x
+
+
+
+---+++Step 1 - Clone the Falcon repository
+
+<verbatim>
+$git clone https://git-wip-us.apache.org/repos/asf/falcon.git falcon
+</verbatim>
+
+
+---+++Step 2 - Build Falcon
+
+<verbatim>
+$cd falcon
+$export MAVEN_OPTS="-Xmx1024m -XX:MaxPermSize=256m -noverify" && mvn clean install
+</verbatim>
+It builds and installs the package into the local repository, for use as a dependency in other projects locally.
+
+[optionally -Dhadoop.version=<<hadoop.version>> can be appended to build for a specific version of Hadoop]
+
+*NOTE:* Falcon drops support for Hadoop-1 and only supports Hadoop-2 from Falcon 0.6 onwards
+[optionally -Doozie.version=<<oozie version>> can be appended to build with a specific version of Oozie. Oozie versions
+>= 4 are supported]
+NOTE: Falcon builds with JDK 1.7/1.8 using -noverify option
+      To compile Falcon with Hive Replication, optionally "-P hadoop-2,hivedr" can be appended. For this Hive >= 1.2.0
+      and Oozie >= 4.2.0 should be available.
+
+
+
+---+++Step 3 - Package and Deploy Falcon
+
+Once the build successfully completes, artifacts can be packaged for deployment using the assembly plugin. The Assembly
+Plugin for Maven is primarily intended to allow users to aggregate the project output along with its dependencies,
+modules, site documentation, and other files into a single distributable archive. There are two basic ways in which you
+can deploy Falcon - Embedded mode(also known as Stand Alone Mode) and Distributed mode. Your next steps will vary based
+on the mode in which you want to deploy Falcon.
+
+*NOTE* : Oozie is being extended by Falcon (particularly on el-extensions) and hence the need for Falcon to build &
+re-package Oozie, so that users of Falcon can work with the right Oozie setup. Though Oozie is packaged by Falcon, it
+needs to be deployed separately by the administrator and is not auto deployed along with Falcon.
+
+
+---++++Embedded/Stand Alone Mode
+Embedded mode is useful when the Hadoop jobs and relevant data processing involve only one Hadoop cluster. In this mode
+ there is a single Falcon server that contacts the scheduler to schedule jobs on Hadoop. All the process/feed requests
+ like submit, schedule, suspend, kill etc. are sent to this server. For running Falcon in this mode one should use the
+ Falcon which has been built using standalone option. You can find the instructions for Embedded mode setup
+ [[Embedded-mode][here]].
+
+
+---++++Distributed Mode
+Distributed mode is for multiple (colos) instances of Hadoop clusters, and multiple workflow schedulers to handle them.
+In this mode Falcon has 2 components: Prism and Server(s). Both Prism and Server(s) have their own their own config
+locations(startup and runtime properties). In this mode Prism acts as a contact point for Falcon servers. While
+ all commands are available through Prism, only read and instance api's are available through Server. You can find the
+ instructions for Distributed Mode setup [[Distributed-mode][here]].
+
+
+
+---+++Preparing Oozie and Falcon packages for deployment
+<verbatim>
+$cd <<project home>>
+$src/bin/package.sh <<hadoop-version>> <<oozie-version>>
+
+>> ex. src/bin/package.sh 1.1.2 4.0.1 or src/bin/package.sh 0.20.2-cdh3u5 4.0.1
+>> ex. src/bin/package.sh 2.5.0 4.0.0
+>> Falcon package is available in <<falcon home>>/target/apache-falcon-<<version>>-bin.tar.gz
+>> Oozie package is available in <<falcon home>>/target/oozie-4.0.1-distro.tar.gz
+</verbatim>
+
+*NOTE:* If you have a separate Apache Oozie installation, you will need to follow some additional steps:
+   1. Once you have setup the Falcon Server, copy libraries under {falcon-server-dir}/oozie/libext/ to {oozie-install-dir}/libext.
+   1. Modify Oozie's configuration file. Copy all Falcon related properties from {falcon-server-dir}/oozie/conf/oozie-site.xml to {oozie-install-dir}/conf/oozie-site.xml
+   1. Restart oozie:
+      1. cd {oozie-install-dir}
+      1. sudo -u oozie ./bin/oozie-stop.sh
+      1. sudo -u oozie ./bin/oozie-setup.sh prepare-war
+      1. sudo -u oozie ./bin/oozie-start.sh

+---+ Operationalizing Falcon
+
+---++ Overview
+
+Apache Falcon provides various tools to operationalize Falcon consisting of Alerts for
+unrecoverable errors, Audits of user actions, Metrics, and Notifications. They are detailed below.
+
+++ Lineage
+
+Currently Lineage has no way to access or restore information about entity instances created during the time lineage
+was disabled. Information about entities however, is preserved and bootstrapped when lineage is enabled. If you have to
+reset the graph db then you can delete the graph db files as specified in the startup.properties and restart the falcon.
+Please note: you will loose all the information about the instances if you delete the graph db.
+
+---++ Monitoring
+
+Falcon provides monitoring of various events by capturing metrics of those events.
+The metric numbers can then be used to monitor performance and health of the Falcon system and
+the entire processing pipelines.
+
+Falcon also exposes [[https://github.com/thinkaurelius/titan/wiki/Titan-Performance-and-Monitoring][metrics for titandb]]
+
+Users can view the logs of these events in the metric.log file, by default this file is created
+under ${user.dir}/logs/ directory. Users may also extend the Falcon monitoring framework to send
+events to systems like Mondemand/lwes by implementingorg.apache.falcon.plugin.MonitoringPlugin
+interface.
+
+The following events are captured by Falcon for logging the metrics:
+   1. New cluster definitions posted to Falcon (success & failures)
+   1. New feed definition posted to Falcon (success & failures)
+   1. New process definition posted to Falcon (success & failures)
+   1. Process update events (success & failures)
+   1. Feed update events (success & failures)
+   1. Cluster update events (success & failures)
+   1. Process suspend events (success & failures)
+   1. Feed suspend events (success & failures)
+   1. Process resume events (success & failures)
+   1. Feed resume events (success & failures)
+   1. Process remove events (success & failures)
+   1. Feed remove events (success & failures)
+   1. Cluster remove events (success & failures)
+   1. Process instance kill events (success & failures)
+   1. Process instance re-run events (success & failures)
+   1. Process instance generation events
+   1. Process instance failure events
+   1. Process instance auto-retry events
+   1. Process instance retry exhaust events
+   1. Feed instance deletion event
+   1. Feed instance deletion failure event (no retries)
+   1. Feed instance replication event
+   1. Feed instance replication failure event
+   1. Feed instance replication auto-retry event
+   1. Feed instance replication retry exhaust event
+   1. Feed instance late arrival event
+   1. Feed instance post cut-off arrival event
+   1. Process re-run due to late feed event
+   1. Transaction rollback failed event
+
+The metric logged for an event has the following properties:
+   1. Action - Name of the event.
+   2. Dimensions - A list of name/value pairs of various attributes for a given action.
+   3. Status- Status of an action FAILED/SUCCEEDED.
+   4. Time-taken - Time taken in nanoseconds for a given action.
+
+An example for an event logged for a submit of a new process definition:
+
+   2012-05-04 12:23:34,026 {Action:submit, Dimensions:{entityType=process}, Status: SUCCEEDED, Time-taken:97087000 ns}
+
+Users may parse the metric.log or capture these events from custom monitoring frameworks and can plot various graphs
+or send alerts according to their requirements.
+
+
+---++ Notifications
+
+Falcon creates a JMS topic for every process/feed that is scheduled in Falcon.
+The implementation class and the broker url of the JMS engine are read from the dependent cluster's definition.
+Users may register consumers on the required topic to check the availability or status of feed instances.
+
+For a given process that is scheduled, the name of the topic is same as the process name.
+Falcon sends a Map message for every feed produced by the instance of a process to the JMS topic.
+The JMS !MapMessage sent to a topic has the following properties:
+entityName, feedNames, feedInstancePath, workflowId, runId, nominalTime, timeStamp, brokerUrl, brokerImplClass, entityType, operation, logFile, topicName, status, brokerTTL;
+
+For a given feed that is scheduled, the name of the topic is same as the feed name.
+Falcon sends a map message for every feed instance that is deleted/archived/replicated depending upon the retention policy set in the feed definition.
+The JMS !MapMessage sent to a topic has the following properties:
+entityName, feedNames, feedInstancePath, workflowId, runId, nominalTime, timeStamp, brokerUrl, brokerImplClass, entityType, operation, logFile, topicName, status, brokerTTL;
+
+The JMS messages are automatically purged after a certain period (default 3 days) by the Falcon JMS house-keeping service.TTL (Time-to-live) for JMS message
+can be configured in the Falcon's startup.properties file.
+
+
+---++ Alerts
+
+Falcon generates alerts for unrecoverable errors into a log file by default.
+Users can view these alerts in the alerts.log file, by default this file is created
+under ${user.dir}/logs/ directory.
+
+Users may also extend the Falcon Alerting plugin to send events to systems like Nagios, etc. by
+extending org.apache.falcon.plugin.AlertingPlugin interface.
+
+
+---++ Audits
+
+Falcon audits all user activity and captures them into a log file by default.
+Users can view these audits in the audit.log file, by default this file is created
+under ${user.dir}/logs/ directory.
+
+Users may also extend the Falcon Audit plugin to send audits to systems like Apache Argus, etc. by
+extending org.apache.falcon.plugin.AuditingPlugin interface.

+---+ Falcon Recipes
+
+---++ Overview
+
+A Falcon recipe is a static process template with parameterized workflow to realize a specific use case. Recipes are
+defined in user space. Recipes will not have support for update or lifecycle management.
+
+For example:
+
+   * Replicating directories from one HDFS cluster to another (not timed partitions)
+   * Replicating hive metadata (database, table, views, etc.)
+   * Replicating between HDFS and Hive - either way
+   * Data masking etc.
+
+---++ Proposal
+
+Falcon provides a Process abstraction that encapsulates the configuration for a user workflow with scheduling
+controls. All recipes can be modeled as a Process with in Falcon which executes the user workflow periodically. The
+process and its associated workflow are parameterized. The user will provide a properties file with name value pairs
+that are substituted by falcon before scheduling it. Falcon translates these recipes as a process entity by
+replacing the parameters in the workflow definition.
+
+---++ Falcon CLI recipe support
+
+Falcon CLI functionality to support recipes has been added.
+<a href="./FalconCLI.html">Recipe command usage is defined here.</a>
+
+CLI accepts recipe option with a recipe name and optional tool and does the following:
+   * Validates the options; name option is mandatory and tool is optional and should be provided if user wants to override the base recipe tool
+   * Looks for <name>-workflow.xml, <name>-template.xml and <name>.properties file in the path specified by falcon.recipe.path in client.properties. If files cannot be found then Falcon CLI will fail
+   * Invokes a Tool to substitute the properties in the templated process for the recipe. By default invokes base tool if tool option is not passed. Tool is responsible for generating process entity at the path specified by FalconCLI
+   * Validates the generated entity
+   * Submit and schedule this entity
+   * Generated process entity files are stored in tmp directory
+
+---++ Base Recipe tool
+
+Falcon provides a base tool that recipes can override. Base Recipe tool does the following:
+   * Expects recipe template file path, recipe properties file path and path where process entity to be submitted should be generated. Validates these arguments
+   * Validates the artifacts i.e. workflow and/or lib files specified in the recipe template exists on local filesystem or HDFS at the specified path else returns error
+   * Copies if the artifacts exists on local filesystem
+      * If workflow is on local FS then falcon.recipe.workflow.path in recipe property file is mandatory for it to be copied to HDFS. If templated process requires custom libs falcon.recipe.workflow.lib.path property is mandatory for them to be copied from Local FS to HDFS. Recipe tool will copy the local artifacts only if these properties are set in properties file
+   * Looks for the patten ##[A-Za-z0-9_.]*## in the templated process and substitutes it with the properties. Process entity generated after the substitution is written to the empty file passed by FalconCLI
+
+---++ Recipe template file format
+
+   * Any templatized string should be in the format ##[A-Za-z0-9_.]*##.
+   * There should be a corresponding entry in the recipe properties file "falcon.recipe.<templatized-string> = <value to be substituted>"
+
+<verbatim>
+Example: If the entry in recipe template is <workflow name="##workflow.name##"> there should be a corresponding entry in the recipe properties file falcon.recipe.workflow.name=hdfs-dr-workflow
+</verbatim>
+
+---++ Recipe properties file format
+
+   * Regular key value pair properties file
+   * Property key should be prefixed by "falcon.recipe."
+
+<verbatim>
+Example: falcon.recipe.workflow.name=hdfs-dr-workflow
+Recipe template will have <workflow name="##workflow.name##">. Recipe tool will look for the patten ##workflow.name##
+and replace it with the property value "hdfs-dr-workflow". Substituted template will have <workflow name="hdfs-dr-workflow">
+</verbatim>
+
+---++ Metrics
+HDFS DR and Hive DR recipes will capture the replication metrics like TIMETAKEN, BYTESCOPIED, COPY (number of files copied) for an
+instance and populate to the GraphDB.
+
+---++ Managing the scheduled recipe process
+   * Scheduled recipe process is similar to regular process
+      * List : falcon entity -type process -name <recipe-process-name> -list
+      * Status : falcon entity -type process -name <recipe-process-name> -status
+      * Delete : falcon entity -type process -name <recipe-process-name> -delete
+
+---++ Sample recipes
+
+   * Sample recipes are published in addons/recipes
+
+---++ Types of recipes
+   * [[HDFSDR][HDFS Recipe]]
+   * [[HiveDR][HiveDR Recipe]]
+
+---++ Packaging
+
+   * There is no packaging for recipes at this time but will be added soon.

+---+ Securing Falcon
+
+---++ Overview
+
+Apache Falcon enforces authentication and authorization which are detailed below. Falcon also
+provides transport level security ensuring data confidentiality and integrity.
+
+
+---++ Authentication (User Identity)
+
+Apache Falcon enforces authentication on protected resources. Once authentication has been established it sets a
+signed HTTP Cookie that contains an authentication token with the user name, user principal,
+authentication type and expiration time.
+
+It does so by using [[http://hadoop.apache .org/docs/current/hadoop-auth/index.html][Hadoop Auth]].
+Hadoop Auth is a Java library consisting of a client and a server components to enable Kerberos SPNEGO authentication
+for HTTP. Hadoop Auth also supports additional authentication mechanisms on the client and the server side via 2
+simple interfaces.
+
+
+---+++ Authentication Methods
+
+It supports 2 authentication methods, simple and kerberos out of the box.
+
+---++++ Pseudo/Simple Authentication
+
+Falcon authenticates the user by simply trusting the value of the query string parameter 'user.name'. This is the
+default mode Falcon is configured with.
+
+---++++ Kerberos Authentication
+
+Falcon uses HTTP Kerberos SPNEGO to authenticate the user.
+
+
+---++ Authorization
+
+Falcon also enforces authorization on Entities using ACLs (Access Control Lists). ACLs are useful
+for implementing permission requirements and provide a way to set different permissions for
+specific users or named groups.
+
+By default, support for authorization is disabled and can be enabled in startup.properties.
+
+---+++ ACLs in Entity
+
+All Entities now have ACL which needs to be present if authorization is enabled. Only owners who
+own or created the entity will be allowed to update or delete their entities.
+
+An entity has ACLs (Access Control Lists) that are useful for implementing permission requirements
+and provide a way to set different permissions for specific users or named groups.

+    <ACL owner="test-user" group="test-group" permission="*"/>
+</verbatim>
+ACL indicates the Access control list for this cluster.
+owner is the Owner of this entity.
+group is the one which has access to read.
+permission indicates the rwx is not enforced at this time.
+
+---+++ Super-User
+
+The super-user is the user with the same identity as falcon process itself. Loosely, if you
+started the falcon, then you are the super-user. The super-user can do anything in that
+permissions checks never fail for the super-user. There is no persistent notion of who was the
+super-user; when the falcon is started the process identity determines who is the super-user
+for now. The Falcon super-user does not have to be the super-user of the falcon host, nor is it
+necessary that all clusters have the same super-user. Also, an experimenter running Falcon on a
+personal workstation, conveniently becomes that installation's super-user without any configuration.
+
+Falcon also allows users to configure a super user group and allows users belonging to this
+group to be a super user.
+
+ACL owner and group must be valid even if the authenticated user is a super-user.
+
+---+++ Group Memberships
+
+Once a user has been authenticated and a username has been determined, the list of groups is
+determined by a group mapping service, configured by the hadoop.security.group.mapping property
+in Hadoop. The default implementation, org.apache.hadoop.security.ShellBasedUnixGroupsMapping,
+will shell out to the Unix bash -c groups command to resolve a list of groups for a user.
+
+Note that Falcon stores the user and group of an Entity as strings; there is no
+conversion from user and group identity numbers as is conventional in Unix.
+
+The only limitation is that a user cannot add a group in ACL that he does not belong to.
+
+---+++ Authorization Provider
+
+Falcon provides a plugin-able provider interface for Authorization. It also ships with a default
+implementation that enforces the following authorization policy.
+
+---++++ Entity and Instance Management Operations Policy
+
+   * All Entity and Instance operations are authorized for users who created them, Owners and users with group memberships
+   * Reference to entities with in a feed or process is allowed with out enforcing permissions
+
+Any Feed or Process can refer to a Cluster entity not owned by the Feed or Process owner. Any Process can refer to a Feed entity not owned by the Process owner
+
+The authorization is enforced in the following way:
+
+   * if admin resource,
+      * If authenticated user name matches the admin users configuration
+      * Else if groups of the authenticated user matches the admin groups configuration
+      * Else authorization exception is thrown
+   * Else if entities or instance resource
+      * If the authenticated user matches the owner in ACL for the entity
+      * Else if the groups of the authenticated user matches the group in ACL for the entity
+      * Else authorization exception is thrown
+   * Else if lineage resource
+      * All have read-only permissions, reason being folks should be able to examine the dependency and allow reuse
+
+To authenticate user for REST api calls, user should append "user.name=<username>" to the query.

+
+---++ Authorization Configuration
+
+---+++ Enabling Authorization
+By default, support for authorization is disabled and specifying ACLs in entities are optional.
+To enable support for authorization, set falcon.security.authorization.enabled to true in the
+startup configuration.
+
+<verbatim>
+# Authorization Enabled flag: false|true
+*.falcon.security.authorization.enabled=true
+</verbatim>
+
+---+++ Authorization Provider
+
+Falcon provides a basic implementation for Authorization bundled, org.apache.falcon.security .DefaultFalconAuthorizationProvider.
+This can be overridden by custom implementations in the startup configuration.
+
+<verbatim>
+# Authorization Provider Fully Qualified Class Name
+*.falcon.security.authorization.provider=org.apache.falcon.security.DefaultAuthorizationProvider
+</verbatim>
+
+---+++ Super User Group
+
+Super user group is determined by the configuration:
+
+<verbatim>
+# The name of the group of super-users
+*.falcon.security.authorization.superusergroup=falcon
+</verbatim>
+
+---+++ Admin Membership
+
+Administrative users are determined by the configuration:
+
+<verbatim>
+# Admin Users, comma separated users
+*.falcon.security.authorization.admin.users=falcon,ambari-qa,seetharam
+</verbatim>
+
+Administrative groups are determined by the configuration:
+
+<verbatim>
+# Admin Group Membership, comma separated users
+*.falcon.security.authorization.admin.groups=falcon,testgroup,staff
+</verbatim>
+
+
+---++ SSL
+
+Falcon provides transport level security ensuring data confidentiality and integrity. This is
+enabled by default for communicating over HTTP between the client and the server.
+
+---+++ SSL Configuration
+
+<verbatim>
+*.falcon.enableTLS=true
+*.keystore.file=/path/to/keystore/file
+*.keystore.password=password
+</verbatim>
+
+---+++ Distributed Falcon Setup
+
+Falcon should be configured to communicate with Prism over TLS in secure mode. Its not enabled by default.
+
+
+---++ Changes to ownership and permissions of directories managed by Falcon
+
+| *Directory*              | *Location*                                                        | *Owner* | *Permissions* |
+| Configuration Store      | ${config.store.uri}                                               | falcon  | 700           |
+| Cluster Staging Location | ${cluster.staging-location}                                       | falcon  | 777           |
+| Cluster Working Location | ${cluster.working-location}                                       | falcon  | 755           |
+| Shared libs              | {cluster.working}/{lib,libext}                                    | falcon  | 755           |
+| Oozie coord/bundle XMLs  | ${cluster.staging-location}/workflows/{entity}/{entity-name}      | $user   | cluster umask |
+| App logs                 | ${cluster.staging-location}/workflows/{entity}/{entity-name}/logs | $user   | cluster umask |
+
+*Note:* Please note that the cluster staging and working locations MUST be created prior to
+submitting a cluster entity to Falcon. Also, note that the the parent dirs must have execute
+permissions.
+
+
+---++ Backwards compatibility
+
+---+++ Scheduled Entities
+
+Entities already scheduled with an earlier version of Falcon are not compatible with this version
+
+---+++ Falcon Clients
+
+Older Falcon clients are backwards compatible wrt Authentication and user information sent as part of the HTTP
+header, Remote-User is still honoured when the authentication type is configured as below:
+
+<verbatim>
+*.falcon.http.authentication.type=org.apache.falcon.security.RemoteUserInHeaderBasedAuthenticationHandler
+</verbatim>
+
+---+++ Blacklisted super users for authentication
+
+The blacklist users used to have the following super users: hdfs, mapreduce, oozie, and falcon.
+The list is externalized from code into Startup.properties file and is empty now and needs to be
+configured specifically in the file.
+
+
+---+++ Falcon Dashboard
+
+To initialize the current user for dashboard, user should append query param "user.name=<username>" to the REST api call.
+
+If dashboard user wishes to change the current user, they should do the following.
+   * delete the hadoop.auth cookie from browser cache.
+   * append query param "user.name=<new_user>" to the next REST API call.
+
+In Kerberos method, the browser must support HTTP Kerberos SPNEGO.
+
+
+---++ Known Limitations
+
+   * ActiveMQ topics are not secure but will be in the near future
+   * Entities already scheduled with an earlier version of Falcon are not compatible with this version as new
+   workflow parameters are being passed back into Falcon such as the user are required
+   * Use of hftp as the scheme for read only interface in cluster entity [[https://issues.apache.org/jira/browse/HADOOP-10215][will not work in Oozie]]
+   The alternative is to use webhdfs scheme instead and its been tested with DistCp.
+
+
+---++ Examples
+
+---+++ Accessing the server using Falcon CLI (Java client)
+
+There is no change in the way the CLI is used. The CLI has been changed to work with the configured authentication
+method.
+
+---+++ Accessing the server using curl
+
+Try accessing protected resources using curl. The protected resources are:
+
+<verbatim>
+$ kinit
+Please enter the password for venkatesh@LOCALHOST:
+
+$ curl http://localhost:15000/api/admin/version
+
+$ curl http://localhost:15000/api/admin/version?user.name=venkatesh
+
+$ curl --negotiate -u foo -b ~/cookiejar.txt -c ~/cookiejar.txt curl http://localhost:15000/api/admin/version
+</verbatim>

+---++ Common CLI Options
+
+---+++Falcon URL
+
+Optional -url option indicating the URL of the Falcon system to run the command against can be provided.  If not mentioned it will be picked from the system environment variable FALCON_URL. If FALCON_URL is not set then it will be picked from client.properties file. If the option is not
+provided and also not set in client.properties, Falcon CLI will fail.
+
+---+++Proxy user support
+
+The -doAs option allows the current user to impersonate other users when interacting with the Falcon system. The current user must be configured as a proxyuser in the Falcon system. The proxyuser configuration may restrict from
+which hosts a user may impersonate users, as well as users of which groups can be impersonated.
+
+<a href="../FalconDocumentation.html#Proxyuser_support">Proxyuser support described here.</a>
+
+---+++Debug Mode
+
+If you export FALCON_DEBUG=true then the Falcon CLI will output the Web Services API details used by any commands you execute. This is useful for debugging purposes to or see how the Falcon CLI works with the WS API.
+Alternately, you can specify '-debug' through the CLI arguments to get the debug statements.
+
+Example:
+$FALCON_HOME/bin/falcon entity -submit -type cluster -file /cluster/definition.xml -debug

+Display the dependent instances which are dependent on the given instance. For example for a given process instance it will
+list all the input feed instances(if any) and the output feed instances(if any).
+
+An example use case of this command is as follows:
+Suppose you find out that the data in a feed instance was incorrect and you need to figure out which all process instances
+consumed this feed instance so that you can reprocess them after correcting the feed instance. You can give the feed instance
+and it will tell you which process instance produced this feed and which all process instances consumed this feed.
+
+NOTE:
+1. instanceTime must be a valid instanceTime e.g. instanceTime of a feed should be in it's validity range on applicable clusters,

+---+FalconCLI
+
+FalconCLI is a interface between user and Falcon. It is a command line utility provided by Falcon. FalconCLI supports Entity Management, Instance Management and Admin operations.There is a set of web services that are used by FalconCLI to interact with Falcon.
+
+---+++Types of CLI Options
+
+CLI options are classified into :
+
+   * <a href="#Common_CLI_Options">Common CLI Options</a>
+   * <a href="#Entity_Management_Commands">Entity Management Commands</a>
+   * <a href="#Instance_Management_Commands">Instance Management Commands</a>
+   * <a href="#Metadata_Commands">Metadata Commands</a>
+   * <a href="#Admin_Commands">Admin commands</a>
+   * <a href="#Recipe_Commands">Recipe commands</a>
+
+
+
+-----------
+
+---++Common CLI Options
+
+---+++Falcon URL
+
+Optional -url option indicating the URL of the Falcon system to run the command against can be provided.  If not mentioned it will be picked from the system environment variable FALCON_URL. If FALCON_URL is not set then it will be picked from client.properties file. If the option is not
+provided and also not set in client.properties, Falcon CLI will fail.
+
+---+++Proxy user support
+
+The -doAs option allows the current user to impersonate other users when interacting with the Falcon system. The current user must be configured as a proxyuser in the Falcon system. The proxyuser configuration may restrict from
+which hosts a user may impersonate users, as well as users of which groups can be impersonated.
+
+<a href="../FalconDocumentation.html#Proxyuser_support">Proxyuser support described here.</a>
+
+---+++Debug Mode
+
+If you export FALCON_DEBUG=true then the Falcon CLI will output the Web Services API details used by any commands you execute. This is useful for debugging purposes to or see how the Falcon CLI works with the WS API.
+Alternately, you can specify '-debug' through the CLI arguments to get the debug statements.
+Example:
+$FALCON_HOME/bin/falcon entity -submit -type cluster -file /cluster/definition.xml -debug

+
+Lookup option tells you which feed does a given path belong to. This can be useful in several scenarios e.g. generally you would want to have a single definition for common feeds like metadata with same location
+otherwise it can result in a problem (different retention durations can result in surprises for one team) If you want to check if there are multiple definitions of same metadata then you can pick
+an instance of that and run through the lookup command like below.
+
+Usage:
+$FALCON_HOME/bin/falcon entity -type feed -lookup -path /data/projects/my-hourly/2014/10/10/23/
+
+If you have multiple feeds with location as /data/projects/my-hourly/${YEAR}/${MONTH}/${DAY}/${HOUR} then this command will return all of them.
