             Summary: Allow dumping of Capacity Scheduler debug logs via web UI 
for a fixed time period
                 Key: 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.
