+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent

+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.

+# Hadoop Authentication Service (HAS)
+A dedicated Hadoop Authentication Server to support various authentication mechanisms other than just Kerberos. In its core it leverages a Kerby KDC developed by [Apache Kerby](https://github.com/apache/directory-kerby), a sub project of [Apache Directory](http://directory.apache.org).
+
+# High level considerations
+* Hadoop services are still strongly authenticated by Kerberos, as Kerberos is the only means so far to enable Hadoop security.
+* Hadoop users can remain to use their familiar login methods.
+* Security admins won't have to migrate and sync up their user accounts to Kerberos back and forth.
+* New authentication mechanism can be customized and plugined.
+
+# Architecture
+![](https://github.com/intel-bigdata/has/blob/release-1.0.0/doc/has-overall.png)
+
+# Design
+Assuming existing users are stored in a SQL database (like MySQL), the detailed design and workflow may go like the following:
+![](https://github.com/intel-bigdata/has/blob/release-1.0.0/doc/has-design.png)
+
+
+# New mechanism plugin API
+
+## HAS client plugin HasClientPlugin:
+
+```Java
+// Get the login module type ID, used to distinguish this module from others. 
+// Should correspond to the server side module.
+String getLoginType()
+
+// Perform all the client side login logics, the results wrapped in an AuthToken, 
+// will be validated by HAS server.
+AuthToken login(Conf loginConf) throws HasLoginException
+```
+
+## HAS server plugin HasServerPlugin:
+
+```Java
+// Get the login module type ID, used to distinguish this module from others. 
+// Should correspond to the client side module.
+String getLoginType()
+
+// Perform all the server side authentication logics, the results wrapped in an AuthToken, 
+// will be used to exchange a Kerberos ticket.
+AuthToken authenticate(AuthToken userToken) throws HasAuthenException
+```

+cd kerby-dist/kdc-dist
+sh bin/kadmin.sh [server-conf-dir] -k [keytab]
+// A.EXAMPLE.COM realm to access a service in the B.EXAMPLE.COM realm
+HadminLocalTool.local: addprinc -pw [same-password] krbtgt/B.EXAMPLE.COM@A.EXAMPLE.COM
+// Make sure that both principals have matching key version numbers and encryption types
+HadminLocalTool.local: getprinc krbtgt/B.EXAMPLE.COM@A.EXAMPLE.COM
+```
+
+### Configure krb5.conf of realms
+
+* config realms and domain_realms sections, make sure the realms are contained.
+
+* config capaths section, which contains the realm chain.
+
+An example of krb5.conf:
+```
+[realms]
+  A.EXAMPLE.COM = {

+  }
+  B.EXAMPLE.COM = {

+## 4. Update the common truststore file
+* Move {trustAll} from node1 to node2 ({trustAll} already has the certificate entry of node1), and repeat Step 3.
+
+* Move the updated {trustAll} from node2 to node1. Repeat these steps for each node in the cluster.
+When you finish, the {trustAll} file will have the certificates from all nodes.

+Deploy SPNEGO
+================
+
+## 1. Server Side Configuration(in server side has-server.conf)
+
+To use Kerberos SPNEGO as the authentication mechanism, the authentication filter must be configured with the following init parameters:
+- filter_auth_type : the keyword kerberos. For example: filter_auth_type = kerberos
+
+## 2. Client Side Configuration(in client side hadmin.conf)
+
+- filter_auth_type the keyword kerberos.  For example: filter_auth_type = kerberos
+- admin_keytab: The path to the keytab file containning the credential for the admin principal. For example: admin_keytab = /etc/has/admin.keytab Here the admin.keytab the same as the server side.
+- admin_keytab_principal: The admin principal. For example: admin_keytab_principal = kadmin/<YOUR-REALM.COM>@<YOUR-REALM.COM>

+High Availability Using MySQL Backend
+========================================
+
+The HAS High Availability feature implemented by providing the option of running two redundant HAS servers. 
+
+## Deployment
+
+### 1. Configure has-server.conf
+
+The two redundant HAS servers must have same https ports. Below are examples:
+
+* has-server.conf of HAS server on emr-header-1:
+```
+[HAS]
+  https_host = emr-header-1
+  https_port = 8092
+  filter_auth_type = kerberos
+  enable_conf = true
+
+[PLUGIN]
+  auth_type = RAM
+```
+
+* has-server.conf of HAS server on emr-worker-1:
+```
+[HAS]
+  https_host = emr-worker-1
+  https_port = 8092
+  filter_auth_type = kerberos
+  enable_conf = true
+
+[PLUGIN]
+  auth_type = RAM
+```
+
+### 2. Start HAS servers
+
+### 3. Configure HAS backend
+
+The two redundant HAS servers must use **mysql** backend, and have same *mysql_url*, *mysql_user* and *mysql_password*.
+
+Please look at [How to use mysql backend](https://github.com/intel-bigdata/has/blob/release-1.0.0/doc/mysql-backend.md) for mysql backend configuration.
+
+### 4. Configure HAS KDC
+
+The two redundant HAS servers must have same ports and realms.
+
+### 5. Start and init HAS KDC servers
+
+> After doing init on either HAS server, the other one has been initialized too.
+>
+> Please keep the shared admin.keytab safely.
+
+### 6. Reexport has-client.conf for HAS web server HA
+
+```
+cd HAS/has-dist
+// Start KDC init tool
+sh bin/kdcinit.sh <conf_dir>
+// Get has-client.conf, and put it to /etc/has:
+KdcInitTool: gethas -p /etc/has
+KdcInitTool: exit
+```
+
+You will get has-client.conf like the following:
+```
+[HAS]
+  https_host = emr-header-1,emr-worker-1
+  https_port = 8092
+  filter_auth_type = kerberos
+  enable_conf = true
+
+[PLUGIN]
+  auth_type = RAM
+```
+
+Hadoop user can use HAS HA feature by updating **core-site.xml** without Reexport has-client.conf.
+add the following properties:
+```
+<property>
+   <name>hadoop.security.has</name>
+   <value>https://emr-header-1:8092/has/v1?auth_type=RAM;https://emr-worker-1:8092/has/v1?auth_type=RAM</value>
+</property>
+```
+
+### 7. Reexport krb5.conf for HAS KDC HA
+
+```
+cd HAS/has-dist
+// Start KDC init tool:
+sh bin/kdcinit.sh <conf_dir>
+// Get krb5.conf, and put it to /etc:
+KdcInitTool: getkrb5 -p /etc
+KdcInitTool: exit
+```
+
+You will get krb5.conf like the following:
+```
+[libdefaults]
+    kdc_realm = HADOOP.COM
+    default_realm = HADOOP.COM
+    udp_preference_limit = 4096
+    kdc_tcp_port = 88
+    kdc_udp_port = 88
+
+[realms]
+    HADOOP.COM = {
+        kdc = localhost:88
+        kdc = localhost:88
+    }
+```
+
+## Verification
+
+You can use login-test tool to verify:
+
+### 1. Update hadmin.conf in <conf_dir>
+
+### 2. Run login-test tool
+```
+cd HAS/has-dist
+// Use tgt to login
+sh bin/login-test.sh tgt <conf_dir>
+```

+# HAS Performance Test Report
+
+## 1. Overview
+
+HAS is a dedicated Hadoop authentication server to support various authentication mechanisms other than just Kerberos. With HAS users can remain their familiar login methods, and new authentication mechanism could be customized and plugined.  
+
+A Hadoop cluster could have thousands of nodes, there maybe so many authentication  requests are sent to HAS server at the same time. So the stability in high concurrency is so important for HAS.
+
+## 2. Test Environment
+
+The test use Alibaba Cloud Elastic Compute Service, detailed test environment like the following: 
+
+### 2.1 Hardware environment
+
+* HAS Server:
+
+> CPU:Intel(R) Xeon(R)CPU E5-2682 @ 2.50GHz    
+> MEM: 16GB    
+> Disk: 43GB 86GB    
+
+* HAS Client:
+
+> CPU:Intel(R) Xeon(R)CPU E5-2682 @ 2.50GHz    
+> MEM: 16GB    
+> Disk: 43GB 86GB * 3
+
+### 2.2 Software environment
+
+> OS: CentOS 7.2    
+> JAVA: 1.8    
+> HAS: 1.0.0    
+> MySQL: 5.5.52  
+
+## 3. Test Method
+
+By using [login-test](https://github.com/Intel-bigdata/HAS/blob/master/has-dist/bin/login-test.sh) scripting tool, the test can be broadly divided into four steps:
+
+1. Add principals to HAS server
+2. Export keytab files to HAS Client  
+    
+    ```shell
+    cd HAS/has-dist         
+    sh bin/login-test add <conf_dir> <work_dir> <principal_num>
+    ```
+
+3. Use keytab files to login concurrently
+
+    ```shell                        
+    sh bin/login-test run <conf_dir> <work_dir> <concurrency_num>
+    ```
+
+4. Record login result and the cost time of login
+
+Testing process like the following:
+
+![testing process](https://user-images.githubusercontent.com/9171954/27905170-b7637602-6271-11e7-8fc9-27d494f9b1ee.jpg)
+
+## 4. Test Result
+
+The test result consists of total cost time and time per request of login using keytab file.
+
+### 4.1 Using Json Backend
+
+| Concurrency | 100 | 500 | 1000 | 5000 | 8000 | 10000 |
+| :---: | :---: | :---: | :---: | :---: | :---: | :---: |
+| Result | Success | Success  | Success  | Success | Success | Success |
+| Total time (ms) | 540 | 1115 | 1661  | 4571 | 6328 | 7208 |
+| Time per request (ms)| 5.400 | 2.230 | 1.661 | 0.914 | 0.791 | 0.721 |
+
+### 4.2 Using MySQL Backend
+
+MySQL Configuration:
+> max connection: 5000              
+> innodb buffer size: 8G
+
+| Concurrency | 100 | 500 | 1000 | 5000 | 8000 | 10000 |
+| :---: | :---: | :---: | :---: | :---: | :---: | :---: |
+| Result | Success | Success  | Success  | Success | Success | Success |
+| Total time (ms) | 765 | 2880  | 4821  | 12712 | 21419 | 22968 |
+| Time per request (ms)| 7.650 | 5.760  | 4.821  | 2.542 | 2.677 | 2.297 |
+
+## 5. Conclusion
+
+![performance in different backends](https://user-images.githubusercontent.com/9171954/27905152-a9bc2a44-6271-11e7-8ddc-16222ee7d3c4.png)
+
+Figure above demonstrates the time per request of HAS authentication in different backends and concurrency. As can be seen, HAS can complete authentication work in high concurrency, and has a good performance. So HAS is good enough for Hadoop.
+
+The CPU utilization and network IO of HAS server are demonstrated in the appendix, with the number of concurrency up to 10000. The appendix shows that HAS server is not under heavy workload in mysql backend.
