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
