    Description

      If hive.exec.parallel is set to true to parallelize MoveTasks or StatsTasks, the Tez task does not benefit from a new thread and will lose all the thread context of the current query.

      Multiple threads even if they are spawned, will lock on SyncDagClient & make progress sequentially.
