Thejas M Nair created HIVE-11407:
------------------------------------

             Summary: JDBC DatabaseMetaData.getTables with large no of tables call leads to HS2 OOM 
                 Key: HIVE-11407
                 URL: https://issues.apache.org/jira/browse/HIVE-11407
             Project: Hive
          Issue Type: Bug
          Components: HiveServer2
            Reporter: Thejas M Nair
            Assignee: Sushanth Sowmyan


With around 7000 tables having around 1500 columns each, and 512MB of HS2 memory, I am able to reproduce this OOM .
Most of the memory is consumed by the datanucleus objects.
