Michael Bieniosek commented on HADOOP-4167:
-------------------------------------------
This affects emacs autosave files. When a buffer is edited, emacs
automatically creates a .#filename file which returns false when java runs an
exists() test. This means that I can't list directories where I have unsaved
emacs buffers open.
> RawLocalFileSystem.listStatus() should not throw FileNotFound exception if a
> file goes missing while the list is being computed

> {{RawLocalFileSystem.listStatus()}} first caches the filenames and then gets
> their statuses. Since there is no directory locking, other processes can
> delete files in between making the cached filenames invalid. Getting the
> filestatus of missing file results into {{FileNotFound}} exception.
