-------------------------------------
Summary: Add metrics to RM for NM heartbeats
Key: MAPREDUCE-4312
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4312
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: mrv2, resourcemanager
Affects Versions: 2.0.0-alpha
Reporter: Jason Lowe
Priority: Minor
It would be nice to have a metric in the ResourceManager to track the number of
NodeManager heartbeats processed. The JobTracker in 1.0 has a tasktracker
heartbeat metric, and it would be nice if the RM had the equivalent metric.
