Luke Lu commented on MAPREDUCE-1779:
------------------------------------
Per discussions with Chris and Arun, the JT memory stats should not be in
ClusterStatus.
> 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.
