-----------------------------------

             Summary: TajoConnection.getSchema() should throw SQLFeatureNotSupportedException.
                 Key: TAJO-1117
                 URL: https://issues.apache.org/jira/browse/TAJO-1117
             Project: Tajo
          Issue Type: Bug
            Reporter: Hyoungjun Kim
            Assignee: Hyoungjun Kim
            Priority: Minor


JDBC has two concepts which are related to the namespace. These are 'catalog' and 'schema'. These concepts are used differently for each database. 
Please check the following the stackoverflow issue.

Currently Tajo uses catalog as database and Tajo doesn't support schema. But Tajo JDBC uses "public" as schema. Tajo should throw SQLFeatureNotSupportedException or return 'null'.
