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.
