[jira] [Created] (HDFS-11628) Clarify behaviors of HDFS Mover in documentation

Xiaobing Zhou created HDFS-11628:
------------------------------------

             Summary: Clarify behaviors of HDFS Mover in documentation
                 Key: HDFS-11628
                 URL: https://issues.apache.org/jira/browse/HDFS-11628
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Xiaobing Zhou
            Assignee: Xiaobing Zhou


It's helpful to state that Mover always tries to move block replicas within the same node whenever possible. If that is not possible (e.g. when a node doesn’t have the target storage type) then it will copy the block replica to another node over the network.
