[jira] [Created] (HDFS-6295) Add "decommissioning" state and node state filtering to dfsadmin

             Summary: Add "decommissioning" state and node state filtering to dfsadmin
                 Key: HDFS-6295
                 URL: https://issues.apache.org/jira/browse/HDFS-6295
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 2.4.0
            Reporter: Andrew Wang
            Assignee: Andrew Wang


One of the few admin-friendly ways of viewing the list of decommissioning nodes is via "hdfs dfsadmin -report". However, this lists *all* the datanodes on the cluster, which is prohibitive for large clusters, and also requires manual parsing to look at the decom status. It'd be nicer if we could fetch and display only decommissioning nodes (or just live and dead nodes for that matter).
