dhruba borthakur updated HADOOP-4435:
-------------------------------------
Attachment: clusterSummary2.patch
1. I would like the JT and NN to display the Heap usage at relatively the same
location. The NN displays the Heap size in the Cluster Summary area. Also, the
values in the Cluster Summary Area keep changing on a live cluster whereas the
header portion (that comprises Started:, Compiledby:, etc) are constant for the
life of a JT. For these reasons, i would like to keep the display of the Heap
Usage in the Cluster Summary portion.
2. I moved FsShell.bytedesc into utils.StringUtils as per your suggestion.
> The JobTracker should display the amount of heap memory used

> It would be nice to make the JobTracker UI display the amount of heap memory
> currently in use. This is similar to the DFS UI that already displays the
> amount if heap memory used by the NameNode.
