Yiqun Lin commented on HDFS-10480:
----------------------------------
Thanks [~manojg] for the great work! Just some thoughts from me.
One case that mentioned above
{quote}
"which open files are blocking server decommissioning"
{quote}
I am thinking we can add a new option like {{-node}} to filter the open files
which under these decommissioning nodes. This will help us find these files and
then we can use command to revoke the lease and close the file. Also we can add
the new option {{-path}} to list a part of files that under the given path and
no need to list all the open files. I suppose these two additional options will
make this command be more useful. If we are agreed on this, I can help make
this improvement in another ticket.
