Vinod K V commented on MAPREDUCE-890:
-------------------------------------
Looked at the patch. Got some comments:
- After patch, at +643, in {{initialize_user()}} function, the patch
incorrectly passes 0 to {{secure_path()}}'s shouldCheckOwnership argument.
- TestTrackerDistributedCacheManager* tests will need modifications too, I
guess.
- It's already a pain running the task-controller tests. With this patch, the
expectation is to run these 5-odd tests with $tt_user and $$non_tt_user, that
is two times. I think we should modify the tests themselves so that this double
test-run is automatically done.
> After HADOOP-4491, the user who started mapred system is not able to run job.
