-------------------------------------
+1 lgtm
On my system the ordering happens to line up, but you're right, there's no
reason it should and it looks like it doesn't on your system.
The Hudson error is HADOOP-7291.

> It seems like the test is assuming that the groups returned by
> UserGroupInformation.getGroupNames() are in the same order as those returned
> by executing `id -Gn`. getGroupNames() only documents that the primary group
> is first, and `man id` doesn't document any ordering, so it seems like the
> test needs to be reworked to remove that assumption.
