Eric Badger commented on YARN-3432:
-----------------------------------

[~brahmareddy], are you still working on this? I would be happy to pick up where the latest
patch left off and add a unit test so that we can get this committed.

> I noticed that when reservations happen when using the Capacity Scheduler, the UI and
web services report the wrong total memory.
> For example.  I have a 300GB of total memory in my cluster.  I allocate 50 and I reserve
10.  The cluster metrics for total memory get reported as 290GB.
> This was broken by https://issues.apache.org/jira/browse/YARN-656 so perhaps there is
a difference between fair scheduler and capacity scheduler.
