Subject [jira] [Created] (MAPREDUCE-4312) Add metrics to RM for NM heartbeats
Date Mon, 04 Jun 2012 22:13:22 GMT
Jason Lowe created MAPREDUCE-4312:

             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.
