Subject [jira] [Commented] (MAPREDUCE-3807) JobTracker needs fix similar to HDFS-94
Date Sun, 06 May 2012 05:44:05 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3807?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13269127#comment-13269127

Harsh J commented on MAPREDUCE-3807:
------------------------------------

Forza,

Sorry for the late response. The logic is sound (and thank you for the patch!), but can you
move the call out to a function inside the JobTrackerJspHelper class, and use that function
here? Or we could factor out a whole new function in a common utils class and use it in both
HDFS and MR to avoid duplication.

> 1.0 JobTracker's jobtracker.jsp page currently shows:
> {code}
> <h2>Cluster Summary (Heap Size is <%= StringUtils.byteDesc(Runtime.getRuntime().totalMemory())
%>/<%= StringUtils.byteDesc(Runtime.getRuntime().maxMemory()) %>)</h2>

> It could use an improvement same as HDFS-94 to reflect live heap usage more accurately.
