Andrew Ferguson commented on MAPREDUCE-4351:
--------------------------------------------
One point I would like feedback on: ContainerManagerImpl's
getContainersMonitor() is only used in NodeManager's init() as part of the call
to createWebServer() --- but with this patch, the ContainersMonitor is now
created locally and passed to the ContainerManager in NodeManager's init().
Does it make sense to remove this function?
thanks!
