Subject [jira] [Commented] (YARN-3294) Allow dumping of Capacity Scheduler debug logs via web UI for a fixed time period
Date Fri, 13 Mar 2015 14:10:38 GMT

    [ https://issues.apache.org/jira/browse/YARN-3294?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14360387#comment-14360387
] 

Varun Vasudev commented on YARN-3294:
-------------------------------------

The findbugs errors are unrelated to the patch. The test failures are also unrelated as per
my analysis and I'm unsure of the Javac warnings since they seem to be from files I didn't
modify. [~jianhe], can you help me out and take a look at the patch?

> It would be nice to have a button on the web UI that would allow dumping of debug logs
for just the capacity scheduler for a fixed period of time(1 min, 5 min or so) in a separate
log file. It would be useful when debugging scheduler behavior without affecting the rest
of the resourcemanager.
