Subject [jira] [Updated] (MAPREDUCE-2984) Throwing NullPointerException when we open the container page
Date Tue, 20 Sep 2011 11:35:09 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-2984?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Devaraj K updated MAPREDUCE-2984:
---------------------------------

    Fix Version/s: 0.24.0
                   0.23.0
           Status: Patch Available  (was: Open)

Issue 1 is not coming in the latest trunk code. 

For issue 2, 
	when the container is null displaying the message saying "Unknown container. Container is
either not yet running or has already completed or doesn't belong to this node at all."  instead
of causing it to NPE.
