We have DFSAdmin command '-setBalancerBandwidth' to dynamically change the max number of bytes per second of network bandwidth to be used by a datanode during balancing. Also add '-setBalancerMaxThreads' to dynamically change the balancer maxThread number which may be used concurrently for moving blocks.
