Attachment: MAPREDUCE-6507.001.patch
The problem is that there is a thread starting the services and the main thread
is asynchronously checking the state. Thus, the main thread checks that the
services are fully up, but they can appear to be started before they have
actually completed their startup (AbstractService sets the state to STARTED
before calling serviceStart()). I think that the easiest fix is to remove the
threads that are spawned from within the main thread that do not appear to
accomplish anything of value.
