> In some use cases, it is desirable to ignore a few data nodes while
> balancing. The administrator should be able to specify a list of data nodes
> in a file similar to the hosts file and the balancer should ignore these data
> nodes while balancing so that no blocks are added/removed on these nodes.
> Similarly it will be beneficial to specify that only a particular list of
> datanodes should be considered for balancing.
