> In order to balance datanode storage utilization of a cluster, Balancer (1)
> classifies datanodes into different groups (overUtilized, aboveAvgUtilized,
> belowAvgUtilized and underUtilized), (2) chooses source and target datanode
> pairs and (3) chooses blocks to move. Some of these logic are in Dispatcher.
> It is better to separate them out. This JIRA is a further work of HDFS-6828.
