Description

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
