We essentially do what you mention - go to the servlet, set the level to DEBUG for the scheduler for some time, set the log level back to INFO, then ask customers to send us the resourcemanager log, and grep/cut out the relevant sections. I was hoping that we could just tell them to click the button, dump the scheduler logs for this brief period of time to a different file and send us the file. > Allow dumping of Capacity Scheduler debug logs via web UI for a fixed time period > --------------------------------------------------------------------------------- > > Key: YARN-3294 > URL: https://issues.apache.org/jira/browse/YARN-3294 > Project: Hadoop YARN > Issue Type: Improvement > Components: capacityscheduler > Reporter: Varun Vasudev > Assignee: Varun Vasudev > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
