> 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.
