Subject [jira] Updated: (MAPREDUCE-488) JobTracker webui should report heap memory used
Date Fri, 21 May 2010 07:33:16 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-488?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Amar Kamat updated MAPREDUCE-488:
---------------------------------

        Summary: JobTracker webui should report heap memory used  (was: ClusterStatus should
report heap memory used)
    Description: As of today JobTracker's webui reports _total-available-heap-memory_ and
_max-heap-memory_. I think it will be useful to show the _actual_ heap memory used i.e {{total
- free}}.   (was: As of today {{ClusterStatus}} reports _total-available-heap-memory_ and
_max-heap-memory_. I think it will be useful to show the _actual_ heap memory used i.e {{total
- free}}. Note that this was introduced by HADOOP-4435.)
