Amareshwari Sriramadasu commented on MAPREDUCE-1186:
----------------------------------------------------
The above proposal looks good for Yahoo! distribution.
In trunk, after MAPREDUCE-856, distributed cache does not need to set any
permissions for LinuxTaskController. Although for the default task controller,
we can set execute permissions as done in pre HADOOP-4490.
> While localizing a DistributedCache file, TT sets permissions recursively on
> the whole base-dir
