Question

我在集群上使用的是kafka v.0.10.2。

我可以使用v.0.8.x和v0.10.2产生很好的消息

但是使用客户端v0.10.0.x消费消息时，但是我在下面出现错误；

WARN [ConsumerFetcherThread-console-consumer-myconsumer-0-1002]，读取kafka.consumer.ConsumerFetcherThread$FetchRequest@16090d7a时出错。可能的原因：java.nio.BufferUnderflowException（kafka.consumer.ConsumerFetcherThread）

好的，现在我的kafka.clien是v.0.8.x 但是我有一个新问题
