Amareshwari Sriramadasu updated MAPREDUCE-1415:
-----------------------------------------------
Attachment: patch-1415-3.txt
Patch adds exists check for the File before doing setExecutable.
Extended the testcase to pass a file in job.jar and validate its permissions
because distributed cache files are set permissions during localization itself,
testcase with distributed cache does not go through the code path of
setExecutable.
All contrib tests passed. TestStreamingAsDifferentUser passed with both tt_user
and some other user.
> With streaming jobs and LinuxTaskController, the localized streaming binary
> has 571 permissions instead of 570
