Jonathan Eagles commented on MAPREDUCE-3175:
--------------------------------------------
Since this change only connected the ACLs to the HttpServer, I have added no
tests since classes inheriting from WebApp are not very testable. Manual tests
confirm /stack /metrics /logs /logLevel /conf and /jmx are not accessible by
other users from RM, NM, HS, and AM.

> RM, NM, job history, and application master httpservers are not created with
> access Control lists. I believe this means that anyone can access any of the
> standard servlets that check to see if the user has administrator access -
> like /jmx, /stacks, etc and ops has no way to restrict access to these things.
