Boyang Chen created KAFKA-9984: ---------------------------------- Summary: Should fail the subscription when pattern is empty Key: KAFKA-9984 URL: https://issues.apache.org/jira/browse/KAFKA-9984 Project: Kafka Issue Type: Bug Components: consumer, streams Reporter: Boyang Chen
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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
