> Separate block replica dispatching from Balancer
> ------------------------------------------------

> Key: HDFS-6828
> URL: https://issues.apache.org/jira/browse/HDFS-6828
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: balancer

>
> 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.
