+***************************
+Backup and Restore Catalog
+***************************
+
+Now, Tajo supports a two backup methods for 
+
+* SQL dump
+* Database-level backup 
+
+==========
+SQL dump 
+==========
+
+SQL dump is an easy and strong way. If you use this approach, you don't need to concern database-level compatibilities. If you want to backup your catalog, just use bin/tajo-dump command. The basic usage of this command is: ::
+
+  $ tajo-dump table_name > outfile
+
+For example, if you want to backup a table customer, you should type a command as follows: ::
+
+  $ bin/tajo-dump customer > table_backup.sql
+  $
+  $ cat table_backup.sql
+  -- Tajo database dump
+  -- Dump date: 10/04/2013 16:28:03
+  --
+
+  --
+  -- Name: customer; Type: TABLE; Storage: TEXT
+  -- Path: file:/home/hyunsik/tpch/customer
+  --
+  CREATE EXTERNAL TABLE customer (c_custkey INT8, c_name TEXT, c_address TEXT, c_nationkey INT8, c_phone TEXT, c_acctbal FLOAT8, c_mktsegment TEXT, c_comment TEXT) USING TEXT LOCATION 'file:/home/hyunsik/tpch/customer';
+  
+
+If you want to restore the catalog from the SQL dump file, please type the below command: ::
+
+  $ bin/tsql -f table_backup.sql
+
+
+If you use an option '-a', tajo-dump will dump all table DDLs. ::
+
+  $ bin/tajo-dump -a > all_backup.sql

+******************************
+Catalog Configuration
+******************************
+
+If you want to customize the catalog service, copy ``$TAJO_HOME/conf/catalog-site.xml.template`` to ``catalog-site.xml``. Then, add the following configs to catalog-site.xml. Note that the default configs are enough to launch Tajo cluster in most cases.
+
+* tajo.catalog.master.addr - If you want to launch a Tajo cluster in distributed mode, you must specify this address. For more detail information, see [Default Ports](#DefaultPorts).
+* tajo.catalog.store.class - If you want to change the persistent storage of the catalog server, specify the class name. Its default value is tajo.catalog.store.DerbyStore. In the current version, Tajo provides three persistent storage classes as follows:
+
++--------------------------------------+------------------------------------------------+
+| Driver Class                         | Descriptions                                   |
++======================================+================================================+
+| tajo.catalog.store.DerbyStore        | this storage class uses Apache Derby.          |
++--------------------------------------+------------------------------------------------+
+| tajo.catalog.store.MySQLStore        | this storage class uses MySQL.                 |
++--------------------------------------+------------------------------------------------+
+| tajo.catalog.store.MariaDBStore      | this storage class uses MariaDB.               |
++--------------------------------------+------------------------------------------------+
+| tajo.catalog.store.MemStore          | this is the in-memory storage. It is only used |
+|                                      | in unit tests to shorten the duration of unit  |
+|                                      | tests.                                         |
++--------------------------------------+------------------------------------------------+
+| tajo.catalog.store.HiveCatalogStore  | this storage class uses HiveMetaStore.         |
++--------------------------------------+------------------------------------------------+
+
+=========================
+Derby Configuration
+=========================
+
+By default, Tajo uses `Apache Derby <http://db.apache.org/derby/>`_ as a persistent storage in order to manage table meta data. So, without any configuration, you can use Derby for catalog store.
+
+Also, you can set manually configs in ``conf/catalog-site.xml`` as follows:
+
+.. code-block:: xml
+
+  <property>
+    <name>tajo.catalog.store.class</name>
+    <value>org.apache.tajo.catalog.store.DerbyStore</value>
+  </property>
+
+  <property>
+    <name>tajo.catalog.uri</name>
+    <value>jdbc:derby:<absolute directory>;create=true</value>
+  </property>
+
+Since Derby is a file-based embedded database, it stores data into a specified directory. So, you need to specify the directory for storing data files instead of specifying JDBC URI with hostname and port. For example, in case where you use '/var/data/tajo-catalog' as a derby store directory, you should set configs as follows:
+
+.. code-block:: xml
+  
+  <property>
+    <name>tajo.catalog.uri</name>
+    <value>jdbc:derby:/var/data/tajo-catalog;create=true</value>
+  </property>
+
+.. warning::
+
+  By default, *Catalog server* stores catalog data into ``/tmp/tajo-catalog-${username}`` directory. But, some operating systems may remove all contents in ``/tmp`` when booting up. In order to ensure persistent store of your catalog data, you need to set a proper location of derby directory.
+
+==================================================
+MySQL/MariaDB/PostgreSQL/Oracle Configuration
+==================================================
+
+Tajo supports several database systems, including MySQL, MariaDB, PostgreSQL, and Oracle, as its catalog store.
+In order to use these systems, you first need to create a database and a user for Tajo.
+The following example shows the creation of a user and a database with MySQL.
+
+.. code-block:: sh
+  
+  mysql> create user 'tajo'@'localhost' identified by 'xxxxxx';
+  Query OK, 0 rows affected (0.00 sec)
+
+  mysql> create database tajo;
+  Query OK, 1 row affected (0.00 sec)  
+
+  mysql> grant all on tajo.* to 'tajo'@'localhost';
+  Query OK, 0 rows affected (0.01 sec)
+
+
+Second, you must install the proper JDBC driver on the TajoMaster node. And then, you need to set the ``TAJO_CLASSPATH`` variable in ``conf/tajo-env.sh`` as follows:
+
+.. code-block:: sh
+
+  (MySQL)
+  $ export TAJO_CLASSPATH=/usr/local/mysql/lib/mysql-connector-java-x.x.x.jar
+
+  (MariaDB)
+  $ export TAJO_CLASSPATH=/usr/local/mariadb/lib/mariadb-java-client-x.x.x.jar
+
+  (PostgreSQL)
+  $ export TAJO_CLASSPATH=/usr/share/java/postgresql-jdbc4.jar
+
+  (Oracle)
+  $ export TAJO_CLASSPATH=/path/to/oracle/driver/ojdbc7.jar
+
+Alternatively, you can copy the jdbc driver into ``$TAJO_HOME/lib``.
+
+Finally, you must add the following configurations to `conf/catalog-site.xml` :
+
+.. code-block:: xml
+
+  <property>
+    <name>tajo.catalog.connection.id</name>
+    <value><user name></value>
+  </property>
+  <property>
+    <name>tajo.catalog.connection.password</name>
+    <value><user password></value>
+  </property>
+
+  <!-- MySQL -->
+  <property>
+    <name>tajo.catalog.store.class</name>
+    <value>org.apache.tajo.catalog.store.MySQLStore</value>
+  </property>
+  <property>
+    <name>tajo.catalog.uri</name>
+    <value>jdbc:mysql://<mysql host name>:<mysql port>/<database name for tajo>?createDatabaseIfNotExist=true</value>
+  </property>
+
+  <!-- MariaDB -->
+  <property>
+    <name>tajo.catalog.store.class</name>
+    <value>org.apache.tajo.catalog.store.MariaDBStore</value>
+  </property>
+  <property>
+    <name>tajo.catalog.uri</name>
+    <value>jdbc:mariadb://<mariadb host name>:<mariadb port>/<database name for tajo>?createDatabaseIfNotExist=true</value>
+  </property>
+
+  <!-- PostgreSQL -->
+  <property>
+    <name>tajo.catalog.store.class</name>
+    <value>org.apache.tajo.catalog.store.PostgreSQLStore</value>
+  </property>
+  <property>
+    <name>tajo.catalog.uri</name>
+    <value>jdbc:postgresql://<postgresql host name>:<postgresql port>/<database name for tajo>?createDatabaseIfNotExist=true</value>
+  </property>
+
+  <!-- Oracle -->
+  <property>
+    <name>tajo.catalog.store.class</name>
+    <value>org.apache.tajo.catalog.store.OracleStore</value>
+  </property>
+  <property>
+    <name>tajo.catalog.uri</name>
+    <value>jdbc:oracle:thin:@//<oracle host name>:<oracle port>/<ServiceName for tajo database></value>
+  </property>
+
+==================================
+HiveCatalogStore Configuration
+==================================
+
+Tajo support HiveCatalogStore to integrate with hive. If you want to use HiveCatalogStore, you just do as follows.
+
+First, you must compile source code and get a binary archive as follows:
+
+.. code-block:: sh
+
+  $ git clone https://git-wip-us.apache.org/repos/asf/tajo.git tajo
+  $ mvn clean install -DskipTests -Pdist -Dtar
+  $ ls tajo-dist/target/tajo-x.y.z-SNAPSHOT.tar.gz
+
+Second, you must set your hive home directory to HIVE_HOME variable in ``conf/tajo-env.sh`` with it as follows:
+
+.. code-block:: sh
+
+  export HIVE_HOME=/path/to/your/hive/directory
+
+Third, if you need to use jdbc to connect HiveMetaStore, you have to prepare mysql jdbc driver on host which can be ran TajoMaster. If you prepare it, you should set jdbc driver file path to ``HIVE_JDBC_DRIVER_DIR`` variable in conf/tajo-env.sh with it as follows:
+
+.. code-block:: sh
+
+  export HIVE_JDBC_DRIVER_DIR=/path/to/your/mysql_jdbc_driver/mysql-connector-java-x.x.x-bin.jar
+
+
+Lastly, you should add the following config to ``conf/catalog-site.xml`` :
+
+.. code-block:: xml
+
+  <property>
+    <name>tajo.catalog.store.class</name>
+    <value>org.apache.tajo.catalog.store.HiveCatalogStore</value>
+  </property>

+Cluster Setup
+*******************************************
+
+Fully Distributed Mode
+==========================================
+A fully distributed mode enables a Tajo instance to run on `Hadoop Distributed File System (HDFS) <http://wiki.apache.org/hadoop/HDFS>`_. In this mode, a number of Tajo workers run across a number of the physical nodes where HDFS data nodes run.
+
+
+In this section, we explain how to setup the cluster mode. 
+
+
+Settings
+--------------------------------------------------------
+
+Please add the following configs to tajo-site.xml file:
+
+.. code-block:: xml
+
+  <property>
+    <name>tajo.rootdir</name>
+    <value>hdfs://hostname:port/tajo</value>
+  </property>
+
+  <property>

+    <name>tajo.catalog.client-rpc.address</name>
+    <value>hostname:26005</value>
+  </property>
+
+Workers
+--------------------------------------------------------
+
+The file ``conf/workers`` lists all host names of workers, one per line.
+By default, this file contains the single entry ``localhost``.
+You can easily add host names of workers via your favorite text editor.
+
+For example: ::
+
+  $ cat > conf/workers
+  host1.domain.com
+  host2.domain.com
+  ....
+
+  <ctrl + d>
+
+Make base directories and set permissions
+--------------------------------------------------------
+
+If you want to know Tajo’s configuration in more detail, see Configuration page.
+Before launching the tajo, you should create the tajo root dir and set the permission as follows: ::
+
+  $ $HADOOP_HOME/bin/hadoop fs -mkdir       /tajo
+  $ $HADOOP_HOME/bin/hadoop fs -chmod g+w   /tajo
+
+
+Launch a Tajo cluster
+--------------------------------------------------------
+
+Then, execute ``start-tajo.sh`` ::
+
+  $ $TAJO_HOME/bin/start-tajo.sh
+
+.. note::
+
+  In default, each worker is set to very little resource capacity. In order to increase parallel degree, please read 
+  :doc:`/configuration/worker_configuration`.
+
+.. note::
+
+  In default, TajoMaster listens on 127.0.0.1 for clients. To allow remote clients to access TajoMaster, please set tajo.master.client-rpc.address config to tajo-site.xml. In order to know how to change the listen port, please refer :doc:`/configuration/service_config_defaults`.

+*********************************
+High Availability for TajoMaster
+*********************************
+
+TajoMaster is a Single Point of Failure in a Tajo Cluster because TajoMaster is the central controlling entity for all components of the Tajo system. TajoMaster failure prevents clients from submitting new queries to the cluster, and results in the disruption of the ability to run insert overwrite queries because the TajoWorker can’t apply its statistical information to CatalogStore. Therefore, the high-availability (HA) of TajoMaster is essential for the high-availability of Tajo generally.
+
+Currently, TajoMaster HA provides the following elements:
+
+* Automatic failover of TajoMaster: Even if the active TajoMaster stops, the standby TajoMaster will become the active node.
+* Preservation of the ongoing query in the cluster: Even if the active TajoMaster stops, the ongoing query will still complete in the cluster.
+
+
+================================================
+  Terminology
+================================================
+
+* Active master: TajoMaster that is actively serving the all operation from TajoClient and TajoWorker.
+* Backup master: This TajoMaster waits becomes active when the Active dies or unhealthy. Users can setup multiple back TajoMaster, and this servers monitors the Active status to become active.
+
+
+================================================
+  Configuration File Settings
+================================================
+
+If you want to use TajoMaster HA mode, specific your ``tajo.master.ha.enable`` as follows:
+
+.. code-block:: xml
+
+  <property>
+    <name>tajo.master.ha.enable</name>
+    <value>true</value>
+  </property>
+
+If you use HA mode, all back masters monitor the active master at 5 second intervals. If you update this period, specific your ``tajo.master.ha.monitor.interval`` as follows:
+
+.. code-block:: xml
+
+  <property>
+    <name>tajo.master.ha.monitor.interval</name>
+    <value>monitor interval</value>
+  </property>
+
+
+================================================
+  Backup Master Settings
+================================================
+
+If you want to run masters with ``start-tajo.sh``, specific your masters in ``conf/masters``. The file lists all host names of masters, one per line.By default, this file contains the single entry ``localhost``. You can easily add host names of workers via your favorite text editor.
+
+For example: ::
+
+  $ cat > conf/masters
+  host1.domain.com
+  host2.domain.com
+  ....
+
+  <ctrl + d>
+
+And then, you need to setup tarball and set configuration files on backup masters.
+
+.. note::
+
+  If you want to run active master and backup master on the same host, you may find TajoMaster port conflicts. To avoid this problem, you must convert backup master primary ports to another port in ``tajo-site.xml`` as follows:
+
+  .. code-block:: xml
+
+    <property>
+      <name>tajo.master.umbilical-rpc.address</name>
+      <value>localhost:36001</value>
+      <description>The default port is 26001.</description>
+    </property>
+
+    <property>
+      <name>tajo.master.client-rpc.address</name>
+      <value>localhost:36002</value>
+      <description>The default port is 26002.</description>
+    </property>
+
+    <property>
+      <name>tajo.resource-tracker.rpc.address</name>
+      <value>localhost:36003</value>
+      <description>The default port is 26003.</description>
+      </property>
+
+    <property>
+      <name>tajo.catalog.client-rpc.address</name>
+      <value>localhost:36005</value>
+      <description>The default port is 26005.</description>
+    </property>
+
+    <property>
+      <name>tajo.master.info-http.address</name>
+      <value>0.0.0.0:36080</value>
+      <description>The default port is 26080.</description>
+    </property>
+
+
+  And you need to convert ``TAJO_PID_DIR`` to another directory in ``tajo-env.sh``.
+
+
+================================================
+  Launch a Tajo cluster
+================================================
+
+Then, execute ``start-tajo.sh`` ::
+
+  $ $TAJO_HOME/bin/start-tajo.sh
+
+.. note::
+
+  You can't use HA mode in DerbyStore. Currently, just one TajoMaster invoke the derby. If another master try to invoke it, it never run itself. Also, if you set another catalog uri for backup master, it is a incorrect configuration. Because they are unequal in every way.
+
+================================================
+  Administration HA state
+================================================
+
+If you want to transit any backup master to active master, execute ``tajo hadmin -transitionToActive`` ::
+
+  $ $TAJO_HOME/bin/tajo haadmin -transitionToActive <target tajo.master.umbilical-rpc.address>
+
+If you want to transit any active master to backup master, execute ``tajo hadmin -transitionToBackup`` ::
+
+  $ $TAJO_HOME/bin/tajo haadmin -transitionToBackup <target tajo.master.umbilical-rpc.address>
+
+If you want to find the state of any master, execute ``tajo hadmin -getState`` ::
+
+  $ $TAJO_HOME/bin/tajo haadmin -getState <target tajo.master.umbilical-rpc.address>
+
+If you want to initiate HA information, execute ``tajo haadmin -formatHA`` ::
+
+  $ $TAJO_HOME/bin/tajo haadmin -formatHA
+
+.. note::
+
+  Before format HA, you must shutdown the Tajo cluster.
+
+
+================================================
+  How to Test Automatic Failover
+================================================
+
+If you want to verify automatic failover of TajoMaster, you must deploy your Tajo cluster with TajoMaster HA enable. And then, you need to find which node is active from Tajo web UI.
+
+Once you find your active TajoMaster, you can cause a failure on that node. For example, you can use kill -9 <pid of TajoMaster> to simulate a JVM crash. Or you can shutdown the machine or disconnect network interface. And then, the backup TajoMaster will be automatically active within 5 seconds. The amount of time required to detect a failure and  trigger a failover depends on the config ``tajo.master.ha.monitor.interval``. If there is running queries, it will be finished successfully. Because your TajoClient will get the result data on TajoWorker. But you can't find already query history. Because TajoMaster stores query history on memory. So, the other master can't access already active master query history. And if there is no running query, the automatic failover run successfully.
+
+.. note::
+
+  TajoMaster HA does not consider TajoWorker failure. It guarantees the high availability of both TajoResourceManager and QueryMaster.

+Preliminary
+***************
+
+===================================
+catalog-site.xml and tajo-site.xml
+===================================
+Tajo's configuration is based on Hadoop's configuration system. Tajo uses two config files:
+
+* catalog-site.xml - configuration for the catalog server.
+* tajo-site.xml - configuration for other tajo modules. 
+
+Each config consists of a pair of a name and a value. If you want to set the config name ``a.b.c`` with the value ``123``, add the following element to an appropriate file.
+
+.. code-block:: xml
+
+  <property>
+    <name>a.b.c</name>
+    <value>123</value>
+  </property>
+
+Tajo has a variety of internal configs. If you don't set some config explicitly, the default config will be used for for that config. Tajo is designed to use only a few of configs in usual cases. You may not be concerned with the configuration.
+
+In default, there is no ``tajo-site.xml`` in ``${TAJO}/conf`` directory. If you set some configs, first copy ``$TAJO_HOME/conf/tajo-site.xml.templete`` to ``tajo-site.xml``. Then, add the configs to your tajo-site.
+
+============
+tajo-env.sh
+============
+
+tajo-env.sh is a shell script file. The main purpose of this file is to set shell environment variables for TajoMaster and TajoWorker java program. So, you can set some variable as follows:
+
+.. code-block:: sh
+
+  VARIABLE=value
+
+If a value is a literal string, type this as follows:
+
+.. code-block:: sh
+

+**************************
+The storage-site.json File
+**************************
+
+This file is for configuring :doc:`/table_management/tablespaces`.
+The syntax of ``storage-site.json`` is like this basically:
+
+.. code:: json
+
+  {
+    "spaces": {
+      <space config 1>, <space config 2>, ...
+    },
+    "storages": {
+      <storage config 1>, <storage config 2>, ...
+    }
+  }
+
+------
+Spaces
+------
+
+This is a section for registering tablespaces. Some space config example is here:
+
+.. code:: json
+
+  "spaces": {
+    "jdbc_pgsql": {
+      "uri": "jdbc:postgresql://127.0.0.1:5740/origin",
+      "configs": {
+        "mapped_database":"tajo_pgsql_origin",
+        "connection_properties": {
+          "user":"tajouser",
+          "password":"123456"
+        }
+      }
+    },
+    ...
+  }
+
+* **space name** : Your own tablespace name which indicates a specific tablespace. Alpha-numeric characters and underscore(_) are permitted.
+* **uri** : An URI address of a tablespace
+* **configs** : It is optional. You can specify it as JSON object to pass to each tablespace handler.
+
+After you specify a tablespace, you can use it in `create table statement <../sql_language/ddl.html#create-table>`_.
+
+--------
+Storages
+--------
+
+This is for registering storage format and custom storage handler class.
+Tajo already supports HDFS, HBase, PostgreSQL, Amazon S3, Openstack Swift, etc, thus in usual cases using mentioned storages, you don't have to add any ``storages`` configuration.
+However, if you want to use your custom storage as one of Tajo's data source, you need to add a configuration for your storage. Here is an example of HDFS storage.
+See :doc:`storage_plugins/overview` for more information.
+
+.. code:: json
+
+  "storages": {
+    "hdfs": {
+      "handler": "org.apache.tajo.storage.FileTablespace",
+      "default-format": "text"
+    },
+    ...
+  }

+Tajo Master Configuration
+**************************
+
+================================================
+  Tajo Rootdir
+================================================
+
+Tajo uses HDFS as a primary storage layer. So, one Tajo cluster instance should have one tajo rootdir. A user is allowed to specific your tajo rootdir as follows:
+
+.. code-block:: xml
+
+  <property>
+    <name>tajo.rootdir</name>
+    <value>hdfs://namenode_hostname:port/path</value>
+  </property>
+
+Tajo rootdir must be a url form like ``scheme://hostname:port/path``. The current implementaion only supports ``hdfs://`` and ``file://`` schemes. The default value is ``file:///tmp/tajo-${user.name}/``.

+Worker Configuration
+*********************
+
+========================
+Worker Heap Memory Size
+========================
+
+The environment variable ``TAJO_WORKER_HEAPSIZE`` in ``conf/tajo-env.sh`` allow Tajo Worker to use the specified heap memory size.
+
+If you want to adjust heap memory size, set ``TAJO_WORKER_HEAPSIZE`` variable in ``conf/tajo-env.sh`` with a proper size as follows:
+
+.. code-block:: bash
+
+  TAJO_WORKER_HEAPSIZE=8000
+
+The default size is 5000 (5GB).
+
+========================
+Temporary Data Directory
+========================
+
+TajoWorker stores temporary data on local file system due to out-of-core algorithms. It is possible to specify one or more temporary data directories where temporary data will be stored.
+
+``tajo-site.xml``
+
+.. code-block:: xml
+
+  <property>
+    <name>tajo.worker.tmpdir.locations</name>
+    <value>/disk1/tmpdir,/disk2/tmpdir,/disk3/tmpdir</value>
+  </property>
+  
+
+==========================================================
+Maximum number of parallel running tasks for each worker
+==========================================================
+
+In Tajo, the capacity of running tasks in parallel are determined by available resources and workload of running queries. In order to specify it, please see [Worker Resources] (#ResourceConfiguration) section.
+
+==========================================================
+Worker Resources
+==========================================================
+
+Each worker can execute multiple tasks simultaneously.
+
+In Tajo, users can specify the number of cpu cores, the total size of memory and the number of disks for each worker. Available resources affect how many tasks are executed simultaneously.
+CPU cores are a unit for expressing CPU parallelism, the unit for memory is megabytes and the unit for disks is the number of disk
+
+In order to specify the resource capacity of each worker, you should add the following configs to ``tajo-site.xml`` :
+
+===================================  =============   ======================   =================================
+  property name                        value type      default value            description
+===================================  =============   ======================   =================================
+  tajo.worker.resource.cpu-cores       Integer         available cpu-cores      the number of cpu cores
+  tajo.worker.resource.memory-mb       Integer         available jvm heap       memory size (MB)
+  tajo.worker.resource.disks           Integer         2                        the number of disks
+  tajo.task.resource.min.memory-mb     Integer         1000                     minimum allocatable memory per task
+  tajo.qm.resource.min.memory-mb       Integer         500                      minimum allocatable memory per query
+===================================  =============   ======================   =================================
+
+.. note:: 
+  
+  Currently, QueryMaster requests 500MB memory and 1 cpu-core per task for the backward compatibility.
+  If you want to give more memory, you can set to ``tajo.qm.resource.min.memory-mb``
+
+.. note::
+
+  If ``tajo.worker.resource.dfs-dir-aware`` is set to ``true`` in ``tajo-site.xml``, the worker will aware of and use the number of HDFS datanode's data dirs in the node.
+  In other words, ``tajo.worker.resource.disks`` is ignored.
+
+------------
+ Example
+------------
+
+Assume that you want to give 15GB Jvm heap, 2GB memory per task, 4 disks, and 12 cores on each worker. The example configuration is as follows:
+
+``tajo-env.sh``
+
+.. code-block:: bash
+
+  export TAJO_WORKER_HEAPSIZE=15000
+
+
+``tajo-site.xml``
+
+.. code-block:: xml
+
+  <property>
+    <name>tajo.worker.resource.cpu-cores</name>
+    <value>12</value>
+  </property>
+  
+   <property>
+    <name>tajo.task.resource.min.memory-mb</name>
+    <value>2000</value>
+  </property>
+  
+  <property>
+    <name>tajo.worker.resource.disks</name>
+    <value>4</value>
+  </property>
+
+
+* Example with HDFS
+
+``tajo-env.sh``
+
+.. code-block:: bash
+
+  export TAJO_WORKER_HEAPSIZE=15000
+
+
+``tajo-site.xml``
+
+.. code-block:: xml
+
+   <property>
+    <name>tajo.task.resource.min.memory-mb</name>
+    <value>2000</value>
+  </property>
+
+  <property>
+    <name>tajo.worker.resource.dfs-dir-aware</name>
+    <value>true</value>
+  </property>
+
+
+* Example with S3
+
+``tajo-env.sh``
+
+.. code-block:: bash
+
+  export TAJO_WORKER_HEAPSIZE=15000
+
+
+``tajo-site.xml``
+
+.. code-block:: xml
+
+   <property>
+    <name>tajo.task.resource.min.memory-mb</name>
+    <value>2000</value>
+  </property>
+
+  <property>
+    <name>tajo.worker.resource.disk.parallel-execution.num</name>
+    <value>4</value>
+  </property>
