    Description

      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.
