BELUGA BEHR updated MAPREDUCE-7155:
-----------------------------------
Status: Patch Available (was: Open)
The MapReduce module is using this class a bit differently than any other
module. The recent changes were causing a NPE in this test. I have addressed
the issue in {{AccessControlList}} and added the appropriate unit tests to
ensure this doesn't happen again.
HADOOP-15836 made a change to keep user and group names in alphabetical order
by way of a {{TreeSet}}. This replaced a {{HashSet}} implementation.
{{HashSet}} allow for a 'null' key and {{TreeSet}} does not.
> TestHSAdminServer is failing
