    Description

      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.
