> 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
