Tajo supports the HiveCatalogStore to integrate with Apache Hive. This integration allows Tajo to access tables in Apache Hive.

Set Environment Variable

Add the following changes to “conf/tajo-env.sh” file.

$ vi conf/tajo-env.sh  
export HIVE_HOME = /path/to/hive

After you have included the Hive path, Tajo will set the Hive library file to the classpath.

Catalog Configuration

Add the following changes to the “conf/catalog-site.xml” file.

$ vi conf/catalog-site.xml  
<property> 
   <name>tajo.catalog.store.class</name> 
   <value>org.apache.tajo.catalog.store.HiveCatalogStore</value> 
</property>

Once HiveCatalogStore is configured, you can access Hive’s table in Tajo.
