[jira] [Created] (HIVE-6828) Hive tez bucket map join conversion interferes with map join conversion

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

             Summary: Hive tez bucket map join conversion interferes with map join conversion
                 Key: HIVE-6828
                 URL: https://issues.apache.org/jira/browse/HIVE-6828
             Project: Hive
          Issue Type: Bug
          Components: Tez
    Affects Versions: 0.13.0, 0.14.0
            Reporter: Vikram Dixit K
            Assignee: Vikram Dixit K


The issue is that bucket count is used for checking the scaled down size of the hash tables but is used later on to convert to the map join as well which may be incorrect in cases where the entire hash table does not fit in the specified size.
