kyungwan nam commented on YARN-6153:
------------------------------------
why I didn’t face the problem above 1 problem in the hadoop-trunk?
It is not intended, but there is already Thread.sleep code to sleep 15 seconds
in the hadoop-trunk.
{code}
//Wait to make sure attempt1 be removed in State Store
//TODO explore a better way than sleeping for a while (YARN-4929)
Thread.sleep(15 * 1000);
{code}
> keepContainer does not work when AM retry window is set

> yarn.resourcemanager.am.max-attempts has been configured to 2 in my cluster.
> I submitted a YARN application (slider app) that keepContainers=true,
> attemptFailuresValidityInterval=300000.
> it did work properly when AM was failed firstly.
> all containers launched by previous AM were resynced with new AM (attempt2)
> without killing containers.
> after 10 minutes, I thought AM failure count was reset by
> attemptFailuresValidityInterval (5 minutes).
> but, all containers were killed when AM was failed secondly. (new AM attempt3
> was launched properly)
