Apache Tajo - Integration with Hive

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.
