Missing cluster level stats on the RM UI
----------------------------------------
Key: MAPREDUCE-2738
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2738
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Affects Versions: 0.23.0
Reporter: Ramya Sunil
Fix For: 0.23.0
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
