[jira] [Created] (HIVE-12905) Issue with mapjoin in tez under certain conditions

Vikram Dixit K created HIVE-12905:
-------------------------------------

             Summary: Issue with mapjoin in tez under certain conditions
                 Key: HIVE-12905
                 URL: https://issues.apache.org/jira/browse/HIVE-12905
             Project: Hive
          Issue Type: Bug
          Components: Tez
    Affects Versions: 1.2.1, 1.0.1, 2.0.0
            Reporter: Vikram Dixit K
            Assignee: Vikram Dixit K


In a specific case where we have an outer join followed by another join on the same key and the non-outer side of the outer join is empty, hive-on-tez produces incorrect results.
