Apache Tajo - Integration with Hive
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 pbrary 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.
