>                 URL: https://issues.apache.org/jira/browse/KAFKA-9984
>             Project: Kafka
>          Issue Type: Bug
>          Components: consumer
>            Reporter: Boyang Chen
>            Priority: Major
>
> We have seen a case where the consumer subscribes to an empty string pattern:
> ```
> [Consumer ...  ] Subscribed to pattern:  ''
> ```
> which doesn't make any sense and usually indicate a configuration error. The `consumer.subscribe(pattern)` call should fail with illegal argument for this case.
