Bikas Saha commented on TEZ-2300:
---------------------------------
The question is whether we want the DAG to stop and containers to be released
or whether we really want the AM to be killed? We need to speed up container
release upon finish for other reasons too.
> TezClient.stop() takes a lot of time or does not work sometimes

> Noticed this with a couple of pig scripts which were not behaving well (AM
> close to OOM, etc) and even with some that were running fine. Pig calls
> Tezclient.stop() in shutdown hook. Ctrl+C to the pig script either exits
> immediately or is hung. In both cases it either takes a long time for the
> yarn application to go to KILLED state. Many times I just end up calling yarn
> application -kill separately after waiting for 5 mins or more for it to get
> killed.
