> {{SCMNodeManager#getNodesByAddress}} is called from
> {{BlockProtocolServer#allocateBlock}} and
> {{BlockProtocolServer#sortDatanodes}}, in both the cases the client could be
> running on a node that's not a datanode. Because of this the SCM log file is
> flooded with {{Cannot find node for address}} messages.
