Я использую kafka v.0.10.2 на своем кластере.
Я могу нормально создавать сообщения, используя v.0.8.x и v0.10.2
НО при использовании сообщений с помощью клиентаv0.10.0.x У меня есть ошибки ниже:
WARN [ConsumerFetcherThread-console-consumer-myconsumer-0-1002], ошибка при получении kafka.consumer.ConsumerFetcherThread$FetchRequest@16090d7a.Возможная причина: java.nio.BufferUnderflowException (kafka.consumer.ConsumerFetcherThread)
хорошо, теперь мой kafka.clien v.0.8.x, но у меня новая проблема
