Hello Apache Kafka community, When using new async KafkaProducer, one can register callback with send calls.
With auto.create.topics.enable set to false, when I try to publish to non existing topic, I expect callback to complete with UnknownTopicOrPartitionException. Instead, I get back "org.apache.kafka.common.errors.TimeoutException: Failed to update metadata after..." When topic doesn't truly exist (so metadata request reached broker and response included error that topic is unknown) I would like to handle that case differently, than when there are e.g. networking problems like when metadata response was not received on time and timeout exception is appropriate. I've reproduced this unwanted behavior with both Kafka 0.9.0.1 and 0.10.1.1 Is this a feature or a bug? If feature, would it make sense to improve it in this case to throw UnknownTopicOrPartitionException instead? Kind regards, Stevo Slavic.
