OK, I think I know what is going on.
We kind of have a mess wrt the zookeeper stuff in the components. I had
originally taken a stab at untangling it, but had problems and reverted back
and scaled back my attempts. Now with my other PR for Yarn and
ZKServerComponents - I'm going to try again.
The issue is that the KafkaWithZK component creates a zkserver, but it
immediately goes out of scope.
I believe that causes the AdminUtils to fail looking up the brokers.
Now that I have a good ZKComponent ( from curator as opposed to the Kafka
testing server one ) I'm going to try again
