> ReplicaPlacementPolicy is already a pluggable component in Hadoop. However,
> the Replica Removal Policy is still nested in BlockManager that need to be
> separated out into a ReplicaPlacementPolicy then can be override later. Also
> it looks like hadoop unit test lack the testing on replica removal policy, so
> we add it here.
> On the other hand, as a implementation of ReplicaPlacementPolicy,
> ReplicaPlacementDefault still show lots of generic for other topology cases
> like: virtualization, and we want to make code in
> ReplicaPlacementPolicyDefault can be reused as much as possible so a few of
> its methods were changed from private to protected.
