Question

我一直在尝试在servicemix中运行Kafka使用者。当我使用mvn camel：run运行时，消费者能够正确运行。但是，与servicekeeper的连接在servicemix中失败，并出现以下错误：

zookeeper和kafka只在我本地计算机上的docker容器内运行。连接在这里不是问题，因为我可以通过端口2181 telnet到zookeeper。我似乎也无法从zookeeper日志获得任何东西。 zookeeper上的日志采用加密格式。有没有办法从servicemix或zookeeper中调试此问题？

任何指针都会非常有用。

Answer 1

我只是快速搜索GSSException，看起来您需要更改servicemix etc / jre.properties文件以导出＆＃34; org.ietf.jgss＆＃34;来自JVM的包。

Answer 2

在Zookeeper Site

提交了一个错误

Kafka使用者无法连接到zookeeper - 服务器null的会话0x0
