Jiangjie Qin commented on KAFKA-3965:
-------------------------------------
Yeah, there is a bug that may cause this problem. We need to set
{{exitOnSendFailure}} to true when producer.send() throws exception. I'll
submit a patch for it. Thanks for reporting this issue.
> Mirror maker sync send fails will lose messages
