> Key: KAFKA-4808
> URL: https://issues.apache.org/jira/browse/KAFKA-4808
> Project: Kafka
> Issue Type: Bug
> Components: producer
> Affects Versions: 0.10.2.0
> Reporter: Ismael Juma
> Assignee: Mayuresh Gharat
> Fix For: 0.11.0.0
>
>
> If a message with a null key is produced to a compacted topic, the broker
> returns `CorruptRecordException`, which is a retriable exception. As such,
> the producer keeps retrying until retries are exhausted or request.timeout.ms
> expires and eventually throws a TimeoutException. This is confusing and not
> user-friendly.
> We should throw a meaningful error back to the user. From an implementation
> perspective, we would have to use a non retriable error code to avoid this
> issue.
