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

             Summary: Disable falling back to non-cbo for SemanticException for tests
                 Key: HIVE-16058
                 URL: https://issues.apache.org/jira/browse/HIVE-16058
             Project: Hive
          Issue Type: Task
          Components: Query Planning
            Reporter: Vineet Garg
            Assignee: Vineet Garg


Currently optimizer falls back to non-cbo path if cbo path throws an exception of type SemanticException.
This might be eclipsing some genuine issues within cbo-path.
We would like to turn off the fall back mechanism for tests to see if there are indeed genuine
issues/bugs within cbo path.
