    Description

      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.
