> we are closing a default session from TezSessionPool at here.
> [https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/exec/tez/TezTask.java#L589]
> If all the sessions in a pool are destroyed, queries wait indefinitely at TezSessionPool.getSession
until HS2 restarts after other service recoveries.
> [HiveServer2-Background-Pool: Thread-12345]: tez.TezSessionPoolManager (:()) - We are
closing a default session because of retry failure.
> It's better if we allow retry & fail than hung.
