Jesse Anderson commented on KAFKA-2961:
---------------------------------------

I understand your point. Maybe changing the method name would connote that it 
isn't additive in a more effective way. Maybe "setTopic(topic)" or 
"setSubscribeTopic(topic)" would be better. Usually a "set..." is not 
considered additive.

> Add a Single Topic KafkaConsumer Helper Function

> To subscribe to a single topic, you need to write more code than you should:
> consumer.subscribe(Arrays.asList(topic));
> There should be a helper function to pass in a single topic to subscribe on. 
> Like this:
> consumer.subscribe(topic);
