[jira] [Updated] (KAFKA-3190) KafkaProducer should not invoke callback in send()

     [ https://issues.apache.org/jira/browse/KAFKA-3190?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Colin P. McCabe updated KAFKA-3190:
-----------------------------------
    Fix Version/s:     (was: 2.3.0)
                   2.4.0

Moving to 2.4.0, since 2.3 seems unlikely at this point.

> 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().
