> HDFS cluster is rack aware.
> Client is in different node than of datanode,
> but Same rack contains one or more datanodes.
> In this case first preference should be given to select 'rack-local' node.
> Currently, since no Node in clusterMap corresponds to client's location,
> blockplacement policy choosing a *random* node as local node and proceeding
> for further placements.
