Description

Per akka documentation - an actor should provide a pattern match for all messages including _ otherwise akka.actor.UnhandledMessage will be propagated.
Noted actors:
MapOutputTrackerMasterActor, ClientActor, Master, Worker...
Should minimally do a
logWarning(s"Received unexpected actor system event: $_") so message info is logged in correct actor.
