Doug Cutting commented on HADOOP-2754:
--------------------------------------
I think perhaps the bug is that ChecksumFileSystem (on which LocalFileSystem is
based) does not implement listStatus(). It has a listPaths() implementation
that filters checksum files. Probably this listPaths() implementation should
be replaced with a listStatus() implementation that filters checksum files.
The default implementation of listPaths() is in terms of listStatus(), so that
will still be filtered. Right now, listStatus() is implemented by the
FilterFileSystem base class, which just forwards to the RawLocalFileSystem, and
thus includes the checksum files.

> If dont pass any filter, it lists paths properly without any .crc files. But
> we write a filter, it does list .crc files also.
