> In order to satisfy storage policy requirement, replication monitor in
> addition reads storage policy information from INodeFile when performing
> replication. As before, it only adds replicas if a block is under
> replicated, and deletes replicas if a block is over replicated. It will NOT
> move replicas around for satisfying storage policy requirement.
