> When Java consumer encounters a corrupt record on a partition it reads from, it throws:
> {code:java}
> org.apache.kafka.common.KafkaException: Received exception when fetching the next record from XYZ. If needed, please seek past the record to continue consumption.

> Caused by: org.apache.kafka.common.errors.CorruptRecordException: Record size is less than the minimum record overhead (14){code}

> 1. Could you consider throwing CorruptRecordException from parseCompletedFetch() when error == Errors.CORRUPT_MESSAGE?
> 2. Seeking past the corrupt record means losing data. I've noticed that the record is often correct on a follower ISR, and manual change of the partition leader to the follower node solves the issue in case partition is used by a single consumer group. Couldn't Kafka server discover such situations and recover corrupt records from logs available on other ISRs somehow?
