Description

Working with the latest trunk version (last commit was on 10/9/2012).

If I create a consumer connector, and create some KafkaStreams using a TopicFilter, but then never send any messages, and then call shutdown on the connector, the KafkaStreams never get notified of the shutdown.

Looking at ZookeeperConsumerConnector, in the method 'sendShutdownToAllQueues', It appears the current implementation is dependent on receiving at least 1 message with a topic, before initializing the list of topicThreadIdAndQueues, to send the shutdownCommand to.
