Brahma Reddy Battula commented on YARN-3432:
--------------------------------------------

[~ajisakaa] thanks a lot for taking a look into this issue..I feel bettter to 
include in {{TotalMB/Containers}} as {{reservedMB/Container}} we are giving as 
metric and it will be clear to user also(even code change looks good since both 
are at same place).let me know your thought on this..

> Cluster metrics have wrong Total Memory when there is reserved memory on CS

> 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.
