[jira] [Updated] (YARN-6153) keepContainer does not work when AM retry window is set

["kyungwan nam (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/YARN-6153?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

kyungwan nam updated YARN-6153:
-------------------------------
    Attachment: YARN-6153.001.patch

if maybeLastAttempt in RMAppAttemptImpl is true, keepContainers is always ignored.
but, after AM reset window time, it is no longer the last attempt.

I'm attaching a patch.
if the last attempt is aged as longer than AM reset window time, the keepContainers will be kept.

> 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)
