Ravi Gummadi commented on MAPREDUCE-1415:
-----------------------------------------

Recursive call of checkPermissionsOnDir() need to send file instead of dir as 
first param. As MAPREDUCE-1435 is also adding the same method and few similar 
methods for checking permissions of private ditributed cache files and public 
distributed cache files, let us regenerate this patch after that(after commit 
of MAPREDUCE-1435).

> With streaming jobs and LinuxTaskController, the localized streaming binary 
> has 571 permissions instead of 570
