             Summary: KafkaConsumer unpauses queues after subscribe()
                 Key: KAFKA-4471
                 URL: https://issues.apache.org/jira/browse/KAFKA-4471
             Project: Kafka
          Issue Type: Bug
          Components: clients
    Affects Versions: 0.10.0.0
            Reporter: Sergey Alaev


How to reproduce:
1. initialize KafkaConsumer and subscribe to some topics by calling `void 
subscribe(Collection<String> topics)`
2. pause some subscribed queues
3. call `void subscribe(Collection<String> topics)` with one more topic
4. paused queues will unpause.

We are using 3-node Kafka cluster, server version = client version = 0.10.0.0.

Note:
There was another problem with 0.9.x - that client did not purge unsubscribed 
queues if they are paused. Probably that got 'fixed'.
