> 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).
