Subject [jira] Commented: (MAPREDUCE-890) After HADOOP-4491, the user who started mapred system is not able to run job.
Date Tue, 02 Feb 2010 09:50:19 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-890?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12828564#action_12828564
] 

Ravi Gummadi commented on MAPREDUCE-890:
----------------------------------------

I don't see much value in changing all LinuxTaskController based tests to take default value
for taskcontroller-ugi when taskcontroller-path is specified(anyway user has to specify taskcontroller-path
for the tests to be run) and taskcontroller-ugi is not specified.
Do you really think it is useful ?
