             Summary: Distinguishing UNION and UNION ALL
                 Key: TAJO-1514
                 URL: https://issues.apache.org/jira/browse/TAJO-1514
             Project: Tajo
          Issue Type: Sub-task
            Reporter: Keuntae Park


Currently, Tajo handles both UNION and UNION ALL as UNION ALL.
For UNION, however, result should not have duplicated rows.
It needs to handle them differently.
