> * While it is possible to implement a custom CopyListing in DistCp, DistCp driver class
doesn't allow for using this custom CopyListing.
> * Allow SimpleCopyListing to provide an option to exclude files (For instance it is useful
to exclude FileOutputCommiter.SUCCEEDED_FILE_NAME during copy as premature copy can indicate
that the entire data is available at the destination)
