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

             Summary: Make dynamic sort partition optimization available to HoS and MR
                 Key: HIVE-20915
                 URL: https://issues.apache.org/jira/browse/HIVE-20915
             Project: Hive
          Issue Type: Bug
          Components: Query Planning
    Affects Versions: 4.0.0
            Reporter: Yongzhi Chen
            Assignee: Yongzhi Chen


HIVE-20703 put dynamic sort partition optimization under cost based decision, but it also makes the optimizer only available to tez. hive.optimize.sort.dynamic.partition works with other execution engines for a long time, we should keep the optimizer available to them.
