> make ResourceTrackerService.nodeHeartbeat more concurrent

>
> We have multiple RPC threads to handle NodeHeartbeatRequest from NMs. By
> design the method ResourceTrackerService.nodeHeartbeat should be concurrent
> enough to scale for large clusters.
> But we have a "BIG" lock in NodesListManager.isValidNode which I think it's
> unnecessary.
> First, the fields "includes" and "excludes" of HostsFileReader are only
> updated on "refresh nodes". All RPC threads handling node heartbeats are
> only readers. So RWLock could be used to alow concurrent access by RPC
> threads.
> Second, since he fields "includes" and "excludes" of HostsFileReader are
> always updated by "reference assignment", which is atomic in Java, the reader
> side lock could just be skipped.
