Attachment: YARN-530-021.patch

This patch manages all the MR services properly -the change was trivial, once 
tracked down. Rather than synchronize on the service itself for state changes, 
we synchronize on a specific {{stateChangeLock}} -ensures that this doesn't 
create any locks elsewhere.

When applied on its own, the YARN changes will successfully run all the 
MapReduce tests except for two in {{TestStagingCleanup}} which are actually due 
to {{ContainerLauncherRouter}} not checking {{containerLauncher}} for nullness 
before stopping -and the shutdown hook calling it in INITED state, not STARTED 
-i.e. is due to the stop() code not being robust enough to stop when not 
started. That's fixed in the main MapReduce patch, because it does add the null 
reference checks

Pulled the {{ServiceShutdownHook}} code off to YARN-679, this eliminates two of 
the FindBugs warnings. The remaining two are spurious as they note that an 
AtomicBool is being used for both a wait/notify barrier as well as for the 
thread-safe get/set operations.

This patch
* includes the static service notification tests of YARN-119
* catches when a service replaces or clones the original configuration it was 
started with, and updates the copy stored in the base service class.
