Amareshwari Sriramadasu commented on MAPREDUCE-1302:
----------------------------------------------------
There is known issue with deletion, see MAPREDUCE-1141. Deletion should not
happen by task localization, it should be done by separate thread in
TaskTracker (CleanupQueue ?).
> TrackerDistributedCacheManager can delete file asynchronously

> With the help of AsyncDiskService from MAPREDUCE-1213, we should be able to
> delete files from distributed cache asynchronously.
> That will help make task initialization faster, because task initialization
> calls the code that localizes files into the cache and may delete some other
> files.
> The deletion can slow down the task initialization speed.
