-----------------------------------

             Summary: KafkaProducer should not invoke callback in send()
                 Key: KAFKA-3190
                 URL: https://issues.apache.org/jira/browse/KAFKA-3190
             Project: Kafka
          Issue Type: Bug
          Components: clients, producer 
    Affects Versions: 0.9.0.0
            Reporter: Jiangjie Qin
            Assignee: Jiangjie Qin
             Fix For: 0.9.0.1


Currently KafkaProducer will invoke callback.onComplete() if it receives an 
ApiException during send(). This breaks the guarantee that callback will be 
invoked in order. It seems ApiException in send() only comes from metadata 
refresh. If so, we can probably simply throw it instead of invoking callback().
