    Description

      We have seen the use case of decommissioning DataNodes that are already dead or unresponsive, and not expected to rejoin the cluster.

      The logic introduced by HDFS-6791 will mark those nodes as DECOMMISSION_INPROGRESS, with a hope that they can come back and finish the decommission work. If an upper layer application is monitoring the decommissioning progress, it will hang forever.
