> ---------------------------------------------------------------------------
>
> Key: YARN-3432
> URL: https://issues.apache.org/jira/browse/YARN-3432
> Project: Hadoop YARN
> Issue Type: Bug
> Components: capacityscheduler, resourcemanager
> Affects Versions: 2.6.0
> Reporter: Thomas Graves
> Assignee: Brahma Reddy Battula
>
> 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.
