Date Wed, 21 Dec 2011 10:19:30 GMT
Add metrics to tasktracker to indicate the number of slots occupied
-------------------------------------------------------------------

                 Key: MAPREDUCE-3589
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3589
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: tasktracker
    Affects Versions: 0.22.0, 0.20.205.0, 0.20.203.0
            Reporter: ade
            Priority: Minor


The number of tasks running on the tasktracker is indicated by maps/reduces_running metrics.
But, if multiple slots occupied by a task(capacity scheduler), we can not get info of the
slot. So, add metrics to tasktracker to indicate the number of slots occupied
