网络是通的,telnet是可以正常访问的,在jmx的9999端口也是可以看到有连接数过来,但是knowstream还是会报这个错误
from knowstreaming.
1 host:wyc.kafka.1.com port:9999.
java.rmi.ConnectException: Connection refused to host: 127.0.0.1; nested exception is:
java.net.ConnectException: Connection refused (Connection refused)
at java.rmi/sun.rmi.transport.tcp.TCPEndpoint.newSocket(TCPEnd
见无数据排查文档,上面有关于JMX连接错误的说明。

@ZQKC 是因为knowstream需要雨kakfa的9999端口需要双向交互的网络开通?

是的。也和配置有关系,具体可以看一下上面提到的那个文档。

@ZQKC 我看官方文档,这里说的,是hostsname配置的问题,是kafka服务端的hostsname还是streaming的hostname的呢?
错误二:错误提示的是127.0.0.1这个IP,这个是机器的hostname配置的可能有问题。
