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

             Summary: Sharedwork optimization should be bypassed for SMB joins
                 Key: HIVE-21760
                 URL: https://issues.apache.org/jira/browse/HIVE-21760
             Project: Hive
          Issue Type: Bug
            Reporter: Vineet Garg
            Assignee: Vineet Garg


SMB join introduces DUMMY OPERATOR, if shared work optimizer merges plan containing dummy operator task generation fails.
I am not sure what is the root cause of failure in task generation but presumably it has some assumption regarding plan containing dummy operator
