Wow!  What a find!  Thank you so much.  You've saved my sanity.  I couldn't fathom how commented-out lines of code would make a difference, but they did, and now I understand why.

> I had a KafkaProducer working fine in 0.9.0.1.  I was having unrelated problems in that version so thought to try 0.10.1.0.  I built it as I did 0.9.0.1:
> Fresh build against Scala 2.11.7.  Built the tgz build plus local maven install.  From the tgz I created a Docker image similar to spotify/kafka.  I linked my producer code to the maven jars.  This process worked in 0.9.
> Code is here:  https://gist.github.com/gzoller/145faef1fefc8acea212e87e06fc86e8
> At the bottom you can see a clip from the output... there's a warning about metadata (not sure if its important or not) and then its trying to send() messages and timing out.  I clipped the output, but it does fail the same way for each message sent in 0.10.1.0.  Same code compiled against 0.9.0.1 populates the topic's partitions w/o problem.
> Was there a breaking change between 0.9 and 0.10, or is this a bug?
