>> Adding a broker after the producer stopped and restarting the producer (consumer still running) throws on the consumer side the InvalidMessageSize exception - which continues to happen on subsequent produce/consume cycles as long as the second broker is running.
What version of Kafka are you running ? Are you using the producer with zk.connect or broker.list ? If you are using broker.list, then you must modify it after deploying a second broker. Is the InvalidMessageSizeException reproducible using our producer/simple-consumer shells ?
