[jira] [Created] (TAJO-2026) Broadcast join tests should be designed precisely with hints

Hyunsik Choi created TAJO-2026:
----------------------------------

             Summary: Broadcast join tests should be designed precisely with hints
                 Key: TAJO-2026
                 URL: https://issues.apache.org/jira/browse/TAJO-2026
             Project: Tajo
          Issue Type: Improvement
            Reporter: Hyunsik Choi


TAJO-2007 changed the planner and optimizer to use the stats stored in catalog. The change affects lots of unit tests, and we found that it is hard to control the join optimization tests in the current approach. 

It can be improved if we introduce the hints and the unit tests are designed precisely with hints.
