> HDFS-10480 adds {{listOpenFiles}} option is to {{dfsadmin}} command to list 
> all the open files in the system.
> One more thing that would be nice here is to filter the output on a passed 
> path or DataNode. Usecases: An admin might already know a stale file by path 
> (perhaps from fsck's -openforwrite), and wants to figure out who the lease 
> holder is. Proposal here is add suboptions to {{listOpenFiles}} to list files 
> filtered by path.
> {{LeaseManager#getINodeWithLeases(INodeDirectory)}} can be used to get the 
> open file list for any given ancestor directory.
