[jira] [Created] (HDFS-16581) Print DataNode node status

JiangHua Zhu created HDFS-16581:
-----------------------------------

             Summary: Print DataNode node status
                 Key: HDFS-16581
                 URL: https://issues.apache.org/jira/browse/HDFS-16581
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: dfsadmin, namenode
    Affects Versions: 3.3.0
            Reporter: JiangHua Zhu


We can use the dfsadmin tool to see which DataNodes the cluster has, and some of these nodes are alive, DECOMMISSIONED, or DECOMMISSION_INPROGRESS. It would be helpful if we could get this information in a timely manner, such as troubleshooting cluster failures, tracking node status, etc.
