--------------------------------------------
Ah... compaction was enabled on that topic for some reason. Than you obviously
need a key, my bad. A different error message would be great nonetheless.
Thanks!

> Project: Kafka
> Issue Type: Bug
> Components: clients
> Affects Versions: 0.10.1.0
> Reporter: Lars Pfannenschmidt

> round-robin fashion.
> {quote}
> {code:title=SomeProducer.java|borderStyle=solid}
> ProducerRecord<String, String> record = new ProducerRecord<>(topic,
> "somemessage");
> return this.producer.send(record).get();
> {code}
> Unfortunately an Exception is thrown:
> {code}
> java.util.concurrent.ExecutionException:
> org.apache.kafka.common.errors.CorruptRecordException: This message has
