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.
> Job.getCounters() returns null when using a cluster
