[jira] [Commented] (YARN-3294) Allow dumping of Capacity Scheduler
debug logs via web UI for a fixed time period
[ https://issues.apache.org/jira/browse/YARN-3294?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14347348#comment-14347348 ]
Jason Lowe commented on YARN-3294:
----------------------------------
Do we really need a dedicated button for a specific system/scheduler when there's already the logLevel applet that let's us control log levels of arbitrary loggers in the process?

> 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.
