Subject [jira] Updated: (HADOOP-4435) The JobTracker should display the amount of heap memory used
Date Mon, 27 Oct 2008 22:33:44 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-4435?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.

> 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.
