Subject [jira] [Commented] (YARN-6153) keepContainer does not work when AM retry window is set
Date Thu, 02 Mar 2017 12:00:51 GMT

    [ https://issues.apache.org/jira/browse/YARN-6153?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15892129#comment-15892129

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}

> 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)
