Gopal V updated HIVE-21646:
---------------------------
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.

the thread context of the current query.
