Manoj Govindassamy commented on HDFS-10480:
-------------------------------------------
[~shahrs87] / [~kihwal],
Thanks for working on this. Very useful. On top of review comments from
[~andrew.wang], I have few more thoughts.
* There are cases where listing open files are needed only under a specific dir
and not the whole system.
* Java API to HdfsAdmin is also very useful for this feature.
* It will be very useful to return/print the open files instead of dumping them
onto a file.
* Testing could add more cases around multiple readers, file opened for
append/truncates, snapshots etc.,
If you are not working on this, can I take up this jira, implement the extra
features, incorporate all review comments and complete the testing ? Please let
me know.

> Currently there is no easy way to obtain the list of active leases or files
> being written. It will be nice if we have an admin command to list open files
> and their lease holders.
