specified
> -----------------------------------------------------------------------------------------------

> Key: KAFKA-5846
> URL: https://issues.apache.org/jira/browse/KAFKA-5846
> Project: Kafka
> Issue Type: Task
> Components: clients
> Reporter: Ted Yu
> Assignee: Kamal Chandraprakash
> Priority: Minor
>
> Currently KafkaConsumer creates instance of NoOpConsumerRebalanceListener for each subscribe()
call where ConsumerRebalanceListener is not specified:
> {code}
> public void subscribe(Pattern pattern) {
> subscribe(pattern, new NoOpConsumerRebalanceListener());
> {code}
> We can create a singleton NoOpConsumerRebalanceListener to be used in such scenarios.
