Hong Tang commented on HADOOP-6198:
-----------------------------------
I'd argue that we may want to support both interfaces. The fact that the
current path-based filtering retrieves a FileStatus object first is an
implementation detail and it is conceivable that a different FS implementation
may be more efficient to support path-based filtering than file-status based
filtering.
> 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.
