Amareshwari Sriramadasu updated MAPREDUCE-1186:
-----------------------------------------------
Attachment: patch-1186-3.txt
Patch incorporating almost all of review comments, except the following two.
bq. I would like to keep the call for cleanupStorage in
TaskTracker.initialize().
Currently, delete for the local directories happens in two places in
initialize(). I removed the second one which is essentailly a no-op earlier.
But now it would delete directories after task-controller's setup.
bq. Remove LOG.info print in DefaultTaskController.initializeDistributedCache.
Instead have a LOG.warn in the exception handler.
I have retained LOG.info statement, it would be helpful in debugging.
> While localizing a DistributedCache file, TT sets permissions recursively on
> the whole base-dir
