Subject [jira] [Commented] (YARN-2900) Application Not Found in AHS throws Internal Server Error with NPE
Date Mon, 24 Nov 2014 22:12:13 GMT

    [ https://issues.apache.org/jira/browse/YARN-2900?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14223621#comment-14223621

Jonathan Eagles commented on YARN-2900:
---------------------------------------

[~zjshen], please don't jump to any conclusions. This is my setup, which I believe is a supported
configuration for 2.6.0.

yarn.timeline-service.generic-application-history.enabled=false
yarn.timeline-service.generic-application-history.store-class=org.apache.hadoop.yarn.server.applicationhistoryservice.NullApplicationHistoryStore
{quote}

The Tez UI make applicationhistory rest api calls to gather fine details for those who have
it enabled. In my case where generic history is disabled, it is causing massive flooding of
log files.

As far as not finding the duplicate JIRA, I was unable to find this issue in the search. Try
to include details that are searchable (stack track, logs, class/file names) so that users
are able to find the appropriate issue.
