Subject [jira] Commented: (MAPREDUCE-1464) In JobTokenIdentifier change method getUsername to getUser which returns UGI
Date Sun, 07 Feb 2010 02:42:28 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1464?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12830616#action_12830616
] 

Jitendra Nath Pandey commented on MAPREDUCE-1464:
-------------------------------------------------

In HADOOP-6510 getUser() is used. It cannot return null if the user is successfully authorized.
Any calls to getUser before the authorization is successful should check for null. Updated
the patch in HADOOP-6510 to handle null returned by getUser before authorization is successful.
