> HDFS-10480 adds {{listOpenFiles}} option is to {{dfsadmin}} command to list
> all the open files in the system.
> Additionally, it would be very useful to only list open files that are
> blocking the DataNode decommissioning. With thousand+ node clusters, where
> there might be machines added and removed regularly for maintenance, any
> option to monitor and debug decommissioning status is very helpful. Proposal
> here is to add suboptions to {{listOpenFiles}} for the above case.
