Hualong Zhang created HDFS-17146:
------------------------------------

             Summary: Use the dfsadmin -reconfig command to initiate 
reconfiguration on all decommissioning datanodes.
                 Key: HDFS-17146
                 URL: https://issues.apache.org/jira/browse/HDFS-17146
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: hdfs
    Affects Versions: 3.4.0
            Reporter: Hualong Zhang
            Assignee: Hualong Zhang


If the *DFSAdmin* command could have the ability to perform bulk operations 
across all decommissioned datanodes, that would be highly advantageous.
