Subject [jira] [Commented] (YARN-7150) Yarn crash [max number of completed apps kept in memory met]
Date Sun, 03 Sep 2017 14:27:02 GMT

    [ https://issues.apache.org/jira/browse/YARN-7150?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16151825#comment-16151825

Daniel Templeton commented on YARN-7150:

That's expected behavior.  YARN has a configurable maximum number of jobs it will keep in
memory and recover from the state store after a failure.  Once that limit is exceeded, you
can find the applications that are no longer available from the resource manager in the application
history server.  Is there some other issue other than the log about hitting the max number
of jobs?  If not, I'll close this as not an issue.
