Date Fri, 19 Feb 2010 05:09:28 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1307?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12835589#action_12835589

Amareshwari Sriramadasu commented on MAPREDUCE-1307:

I looked at the console output for TestJobRetire. The timeout is because of HADOOP-6528.
Corresponding console log:

> It would be good to define the notion of job permissions analogous to file permissions.
Then the JobTracker can restrict who can "read" (e.g. look at the job page) or "modify" (e.g.
kill) jobs.
