Sergey Shelukhin commented on HIVE-16114:
-----------------------------------------
The patch makes sense to me... I wonder though how a closed session state ends
up there. Can you add a warning if the session is closed? Might be worth
checking and adding it even in TezTask, near the "Need to remove this static
hack" comment :)
> NullPointerException in TezSessionPoolManager when getting the session
