Hemanth Yamijala commented on HADOOP-4491:
------------------------------------------
I missed out one more point. In initialize_job we should be setting the
permissions as 2570 recursively. Only the work directory needs to open up write
for the user.
> Per-job local data on the TaskTracker node should have right access-control
