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

             Summary: JOIN operator should update the column stats when number of rows changes
                 Key: HIVE-7679
                 URL: https://issues.apache.org/jira/browse/HIVE-7679
             Project: Hive
          Issue Type: Sub-task
    Affects Versions: 0.14.0
            Reporter: Prasanth J
            Assignee: Prasanth J
            Priority: Minor


JOIN operator does not update the column stats when the number of rows changes. All other
operators scales up/down the column statistics when the number of rows changes. Same should
be done for JOIN operator as well.
