Hi folks,
I don't really know where to put this information, but I just made a small sample project on how to use this Tap/Sink on Hortonworks 2.4.
It is available here:

... maybe you want to add it as a note somewhere. It took me quite a time to resolve all runtime conflicts with the provided libraries thus it should be helpful as a start for others.
Best,
André
