Robert Joseph Evans commented on MAPREDUCE-2738:
------------------------------------------------

Thanks for fixing the tests.  I forgot to run them after making my change, and since I added
in new columns to the data the number of tds changed.  My bad.  Your changes to the patch
look good.  +1

> Cluster usage information such as the following are currently not available in the RM
UI. 
> - Total number of apps submitted so far
> - Total number of containers running/total memory usage 
> - Total capacity of the cluster (in terms of memory)
> - Reserved memory
> - Total number of NMs - sorting based on Node IDs is an option but when there are lost
NMs or restarted NMs, the node ids does not correspond to the actual value
> - Blacklisted NMs - sorting based on health-status and counting manually is not very
straight forward
> - Excluded NMs
> - Handle to the jobhistory server
