Doug Cutting commented on HADOOP-6198:
--------------------------------------
> We'll have to keep PathFilter around for at least another release for
> backwards-compatibility, but I'd like to deprecate it.
+1 We've generally tried to switch FileSystem APIs from using Path to
FileStatus whereever possible, deprecating and eventually removing Path-based
methods, and this just seems like a case we've missed.
> FileSystem filtering should work on FileStatus rather than Path objects

> There's an avoidable overhead in listing/globbing items with some property
> (e.g. owned by user foo, only files, files larger than _n_ bytes, etc.).
> Internally, the Path is extracted from a FileStatus object and passed to the
> PathFilter; simply passing the FileStatus object would allow one to filter on
> the information in the status object.
