[jira] [Created] (HIVE-8724) Right outer join produces incorrect result on Tez

Gunther Hagleitner created HIVE-8724:
----------------------------------------

             Summary: Right outer join produces incorrect result on Tez
                 Key: HIVE-8724
                 URL: https://issues.apache.org/jira/browse/HIVE-8724
             Project: Hive
          Issue Type: Bug
            Reporter: Gunther Hagleitner
            Assignee: Gunther Hagleitner
            Priority: Critical
             Fix For: 0.14.0


Still working on repro. But when testing h14 in the cluster I've seen some errors with right outer joins. Rewriting as left outer joins works fine. It seems that when initializing the groups in CommonMergeJoinOperator the state machine gets confused about what position in the stream we're at.
