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
