> The datanode receives data from a client write request or from a replication 
> request. It is useful to configure the cluster to so that dedicated bandwidth 
> is allocated for client writes and replication traffic. This requires that 
> the client-writes and replication traffic be configured to operate on two 
> different ports to the datanode.
