Amareshwari Sriramadasu commented on MAPREDUCE-1186:
----------------------------------------------------
bq. Move securing the cache file path in the same code path as where
localization of the cache files happens.
We should do this for the correctness part, as Hemanth pointed out.
Hemanth, if we are doing the above, current directory structure is still fine,
right? We need not introduce task-id in the directory structure. The patch
will be replacing current FileUtil.chmod call with the call to TaskController.
Does it make sense?
