             Summary: Add RecordMetadataNotAvailableException to indicate that ProduceResponse did not contain offset and timestamp information
                 Key: KAFKA-5913
                 URL: https://issues.apache.org/jira/browse/KAFKA-5913
             Project: Kafka
          Issue Type: Sub-task
            Reporter: Apurva Mehta
            Assignee: Apurva Mehta
             Fix For: 1.0.0


One of the changes in KIP-192 is to send a {{DUPLICATE_SEQUENCE}} error code with a {{ProduceResponse}} when we detect a duplicate on the broker but don't have the batch metadata for the sequence in question in memory.

To handle this on the client, we mark the batch as successful, but cannot return the offset and timestamp information in the {{RecordMetadata}} returned in the produce future. Instead of returning implicit invalid values (like -1), we should throw a {{RecordMetadataNotAvailableException}} to ensure that applications don't suffer from faulty processing.
