Vinod K V commented on MAPREDUCE-1415:
--------------------------------------
Note that this still isn't a major security concern as all the parent
directories are secure already. This fix is needed so we are consistent with
permissions overall.
> With streaming jobs and LinuxTaskController, the localized streaming binary
> has 571 permissions instead of 570
