Sandy Ryza commented on YARN-1221:
----------------------------------
bq. The reason I removed the code above is that there is no corresponding
unreserve method got called.
Good catch. But that shouldn't affect the amount shown in the web UI, because
the metrics for which there is double counting are the leaf queue metrics,
whereas the value in the web UI is based only off of the root queue metrics.
Is that not right?
bq. As far as I saw from the webUI, the available memory never get decremented
when it allocates memory to mr jobs.
Where are you seeing the available memory reported on the web UI?
To be clear, I'm referring to what's shown under the "Cluster Metrics" section
when you go to http://<rmhost>:<port>/cluster
> With Fair Scheduler, reserved MB reported in RM web UI increases indefinitely
