Hemanth Yamijala commented on HADOOP-4782:
------------------------------------------
Actually, thinking about this... I think we need two patches.
1 for trunk, where we revert the umask patch and leave it at that.
The second one is for the 18 branch alone where we turn on permissions for the
history file. For this one, I can use hadoop-4782v1.txt attachment. It looks
good.
Please upload a patch for trunk reverting the umask fix alone. Note, that
should not have any other changes.

> In HADOOP-4705, we fixed hod to grant read access to all directories and
> files that HOD creates, and also set the umask such that files created by
> Hadoop also get read permissions to world. In shared clusters, this is
> opening up too much to the users. This issue is for resetting the permissions
> to be as constrained as possible, while still addressing the requirement
> raised in HADOOP-4705.
