      Description

      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).
