MAPREDUCE-5014

[Mathieu CHATAIGNER]

Hello,

I would like to create a custom distcp CopyListing however it is not
possible to do it outside of package org.apache.hadoop.tools since both
exceptions DuplicateFileException and InvalidInputException are packaged
scope.

I attached a patch to make those exception public to solve this issue.
I don't know if I need to create an issue or update
https://issues.apache.org/jira/browse/MAPREDUCE-5014

Thanks.
