Should we provide a way to know JobTracker's memory info from client?
---------------------------------------------------------------------

                 Key: MAPREDUCE-1779
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1779
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: client, jobtracker
    Affects Versions: 0.21.0
            Reporter: Amareshwari Sriramadasu
             Fix For: 0.22.0


In HADOOP-4435, in branch 0.20, getClusterStatus() method returns JobTracker's used memory
and total memory.
But these details are missed in new api (through MAPREDUCE-777).
If these details are needed only for web UI, I don't think they are needed for client.
So, should we provide a way to know JobTracker's memory info from client?
If yes, an api should be added in org.apache.hadoop.mapreduce.Cluster for the same.
