--------------------------------------
Attachment: HADOOP-12566.002.patch
Thanks, [ozawa]. For some reason I'm not seeing the unchecked compile errors
when I build locally with Maven, but I was able to see them running javac by
hand.
Here's a patch with the issue resolved.
> Add NullGroupMapping

> Add a {{NullGroupMapping}} for cases where user groups are not used.
> {{ShellBasedUnixGroupMapping}} can be used in places where latency is not
> important. In places like starting a container, it's worth in to avoid the
> extra fork and exec.
