    核心报错信息:

    EndOfStreamException: Unable to read additional data from client sessionid 0x6362257b44e5068d, likely client has closed socket

    具体问题所在:

    客户端连接Zookeeper时,配置的超时时长过短。致使Zookeeper还没有读完Consumer的数据,连接就被Consumer断开了。

    解决方案:

    初始化Zookeeper连接时,将接收超时参数值调整大一些即可(tickTime2000改为10000),默认是毫秒(ms)
