Siddharth Seth commented on YARN-71:
------------------------------------

Comments on the latest patch.

- timestamp can moce out - so that the same ts is used across all local dirs.
- Instead of scheduling old files, then renaming the current files and scheduling additional
deletes - this could change to just rename the current files, and schedule deletion once.
In the unit test
