----------------------------------
Summary: Blocks on DECOMMISSIONING DNs should be sorted properly
in LocatedBlocks
Key: HDFS-17091
URL: https://issues.apache.org/jira/browse/HDFS-17091
Project: Hadoop HDFS
Issue Type: Improvement
Components: hdfs
Reporter: WangYuanben
Assignee: WangYuanben
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.
