Can you tell me specifically what you noticed in the Kafka bundle.  It
seems like we should be totally safe when depending on another Apache
Software Foundation project.  However, perhaps that is a dangerous

I looked up Kafka's NOTICE and LICENSE file and appears to be the stock
one.  However, I then looked up the scala dependency which comes in from
using their client and it looks like a typical 3-clause BSD license which
should be called out in the overall license.  Will look further but would
like to know what you found as well.
