  • 贬了 applekafka 消费者消费不到数据 的评论!

    第二个你的消费者组没有注册上去,你得详细描述一下,另起一个问题吧。

  • 赞了 applekafka生产数据时报TimeoutException异常 的评论!

    错误信息太多了,但是重要信息太少。

    我姑且认为你是有多台生产机器,其中有部分是报timeout的,有部分是可用的。而且生产机器是网络环境是一致的情况下。

    从日志来看,java.nio.channels.ClosedChannelException

    这个错误很明显了,就是网络问题。

    排查:
    1、检查所有生产者机器与集群地址是否是ok的。
    2、排查集群的配置是否有问题。
    3、防火墙问题,部分防火墙短连接是ok的,但是会kill长连接
