Major Description
I'm porting some unit tests from 0.7.2 to 0.8.0. The test does the following, all embedded in the same java process:
– spins up a zk instance
– spins up a kafka server using a fresh log directory
– creates a producer and sends a message
– creates a high-level consumer and verifies that it can consume the message
– shuts down the consumer
– stops the kafka server
– stops zk
The test seems to be working fine now, however, I consistently see the following exception, when the consumer connector is shutdown:

It would be great if instead, something meaningful was logged, like:
"Consumer connector has been shutdown"
