Vinod K V commented on MAPREDUCE-1421:
--------------------------------------

Looked at the patch. It has missed some cases:
 - TestKillSubProcessesWithLinuxTaskController will also fail, but only if the 
group-owner of the binary is TT's non-primary group (which is typically the 
clusters' setup).
 - TestJobExecutionAsDifferentUser.testTimeoutStackTrace() has to run the job 
as proxy user.

To help future tests, should we describe in the javadoc of 
ClusterWithLinuxTaskController as to how one should run jobs as other users in 
the tests?

Can we also change the remaining "/testing/" paths in TestPipes to "testing/" 
so that we are consistent throughout the test-case?
