 Mover - A New Data Migration Tool
 ---------------------------------
 
-A new data migration tool is added for archiving data. The tool is similar to Balancer. It
periodically scans the files in HDFS to check if the block placement satisfies the storage
policy. For the blocks violating the storage policy, it moves the replicas to a different
storage type in order to fulfill the storage policy requirement.
+A new data migration tool is added for archiving data. The tool is similar to Balancer. It
periodically scans the files in HDFS to check if the block placement satisfies the storage
policy. For the blocks violating the storage policy, it moves the replicas to a different
storage type in order to fulfill the storage policy requirement. Note that it 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 replicas to
another node over the network.
