-------------------------------------
Summary: A ConsumerConnector that never receives messages does not
shutdown cleanly
Key: KAFKA-602
URL: https://issues.apache.org/jira/browse/KAFKA-602
Project: Kafka
Issue Type: Bug
Affects Versions: 0.8.1
Reporter: Jason Rosenberg
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.
