Hi Jun,
I didn't find any error in producer log.
I did another test, first I injected data to kafka server, then stop
producer, and start consumer.
The exception still happened, so the exception is not related with producer.
>From the log below, it seems consumer exception happened first.
*
Exceptions in consumers:*
