Seems this JIRA can be resolved. Closed this.
Hi [~manojg], as I see this patch was committed, I have rebased the patch in
HDFS-11848. It would be nice to implement list files under given path as well.
Please have a look when you get a chance.

> 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.
