Resolution: Duplicate
> "Exactly-once" stream breaks production exception handler contract
> ------------------------------------------------------------------
>
> Key: KAFKA-7108
> URL: https://issues.apache.org/jira/browse/KAFKA-7108
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 1.1.0
> Reporter: Anna O
> Priority: Major
> Labels: exactly-once
>
> I have a stream configured with "default.production.exception.handler" that
> is supposed to log the error and continue. When I set "processing.guarantee"
> to "exactly_once" it appeared that retryable NotEnoughReplicasException that
> passed the production exception handler was rethrown by the
> TransactionManager wrapped with KafkaException and terminated the stream
> thread:
> _org.apache.kafka.common.KafkaException: Cannot execute transactional method
> because we are in an error stateat
