Zoltan Haindrich created HIVE-19854:
---------------------------------------

             Summary: investigate tez_smb_main.q result difference
                 Key: HIVE-19854
                 URL: https://issues.apache.org/jira/browse/HIVE-19854
             Project: Hive
          Issue Type: Bug
            Reporter: Zoltan Haindrich


found while working on HIVE-19824:
tez_smb_main.q.out seems to give different results for the following query if the join is executed by a merge join

{code}
select count(*) from tab_n11 a join tab_part_n12 b on a.key = b.key join src1 c on a.value = c.value
{code}

old result: 9
mergejoin result: 40
