Mathieu Chataigner commented on MAPREDUCE-5014:
-----------------------------------------------
I don't know if I need to create a new issue or re-open this one, but there is
no way to extends CopyListing outside of package org.apache.hadoop.tools since
both exceptions DuplicateFileException and InvalidInputException are packaged
scope.
> Extending DistCp through a custom CopyListing is not possible

> * 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)
