> The Balancer class implements two major features, (1) balancing logic for selecting replicas
in order to balance the cluster and (2) block replica dispatching for moving the block replica
around.  This JIRA is to separate (2) from Balancer so that the code could be reused by other
code such as the new data migration tool proposed in HDFS-6801.
