[jira] Commented: (MAPREDUCE-1920) Job.getCounters() returns null when using a cluster

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1920?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12896457#action_12896457 ] 

Amareshwari Sriramadasu commented on MAPREDUCE-1920:
----------------------------------------------------

I see that patch adds conf.setUser(UserGroupInformation.getCurrentUser().getUserName()) in JobConf for many testcases. I did not understand why is that needed here. I ran TestTrackerReservation and TestClusterStatus with the attached patch, the tests are still failing.
