Mayuresh Gharat commented on KAFKA-4808: ---------------------------------------- [~ijuma] Sure we can provide a better error message if we have a separate Error_Code. It looks like a subclass of InvalidRequestException as its indeed an invalid produce request for that topic. I will work on the KIP. Thanks, Mayuresh > send of null key to a compacted topic should throw error back to user > --------------------------------------------------------------------- > > 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: 0.10.3.0 > > > 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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
