> Being similar to 
> [HDFS-16076|https://issues.apache.org/jira/browse/HDFS-16076], I think 
> decommissioning DNs needs to be taken into consideration. After sorting the 
> expected location list will be: live -> slow -> stale -> staleAndSlow -> 
> entering_maintenance -> decommissioned -> decommissioning.
