>                 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
>            Assignee: Vahid Hashemian
>
> How to reproduce:
> 1. initialize KafkaConsumer and subscribe to some topics by calling `void subscribe(Collection<String> topics)`
> 2. pause some subscribed partitions
> 3. call `void subscribe(Collection<String> topics)` with one more topic
> 4. paused partitions will unpause.
> We are using 3-node Kafka cluster, server version = client version = 0.10.0.0., one partition per topic
> Note:
> There was another problem with 0.9.x - that client did not purge unsubscribed queues if they are paused. Probably that got 'fixed'.
