Tajo⢠catalog supports HCatalogStore driver to integrate with Apache Hiveâ¢. +This integration allows Tajo to access all tables used in Apache Hive. +Depending on your purpose, you can execute either SQL queries or HiveQL queries on the +same tables managed in Apache Hive.</p> +<p>In order to use this feature, you need to build Tajo with a specified maven profile +and then add some configs into <tt class="docutils literal"><span class="pre">conf/tajo-env.sh</span></tt> and <tt class="docutils literal"><span class="pre">conf/catalog-site.xml</span></tt>. +This section describes how to setup HCatalog integration. +This instruction would take no more than ten minutes.</p> +<p>First, you need to compile the source code with hcatalog profile. +Currently, Tajo supports hcatalog-0.11.0 and hcatalog-0.12.0 profile. +So, if you want to use Hive 0.11.0, you need to set <tt class="docutils literal"><span class="pre">-Phcatalog-0.11.0</span></tt> as the maven profile</p> +<div class="highlight-python"><div class="highlight"><pre>$ mvn clean package -DskipTests -Pdist -Dtar -Phcatalog-0.11.0 +</pre></div> +</div> +<p>Or, if you want to use Hive 0.12.0, you need to set <tt class="docutils literal"><span class="pre">-Phcatalog-0.12.0</span></tt> as the maven profile</p> +<div class="highlight-python"><div class="highlight"><pre>$ mvn clean package -DskipTests -Pdist -Dtar -Phcatalog-0.12.0 +</pre></div> +</div> +<p>Then, you need to set your Hive home directory to the environment variable <tt class="docutils literal"><span class="pre">HIVE_HOME</span></tt> in conf/tajo-env.sh as follows:</p> +<div class="highlight-python"><div class="highlight"><pre>export HIVE_HOME=/path/to/your/hive/directory +</pre></div> +</div> +<p>If you need to use jdbc to connect HiveMetaStore, you have to prepare MySQL jdbc driver. +Next, you should set the path of MySQL JDBC driver jar file to the environment variable HIVE_JDBC_DRIVER_DIR in conf/tajo-env.sh as follows:</p> +<div class="highlight-python"><div class="highlight"><pre>export HIVE_JDBC_DRIVER_DIR==/path/to/your/mysql_jdbc_driver/mysql-connector-java-x.x.x-bin.jar +</pre></div> +</div> +<p>Finally, you should specify HCatalogStore as Tajo catalog driver class in <tt class="docutils literal"><span class="pre">conf/catalog-site.xml</span></tt> as follows:</p> +<div class="highlight-python"><div class="highlight"><pre><property> + <name>tajo.catalog.store.class</name> + <value>org.apache.tajo.catalog.store.HCatalogStore</value> +</property> +</pre></div> +</div> +<div class="admonition note">

Tajo to access all tables used in Apache Hive. +Depending on your purpose, you can execute either SQL queries or HiveQL queries on the +same tables managed in Apache Hive.</p> +<p>In order to use this feature, you need to build Tajo with a specified maven profile +and then add some configs into <code class="docutils literal"><span class="pre">conf/tajo-env.sh</span></code> and <code class="docutils literal"><span class="pre">conf/catalog-site.xml</span></code>. +This section describes how to setup HiveMetaStore integration. +This instruction would take no more than five minutes.</p> +<p>You need

class="highlight"><pre>export HIVE_JDBC_DRIVER_DIR==/path/to/your/mysql_jdbc_driver/mysql-connector-java-x.x.x-bin.jar +</pre></div> +</div> +<p>Finally, you should specify HiveCatalogStore as Tajo
