答

你看第二行，已经告诉你异常了。“Disconnected while requesting ApiVersion: might be caused by incorrect security.protocol configuration (connecting to a SSL listener?) or broker version is < 0.10 (see api.version.request) (after 1ms in state APIVERSION_QUERY)”
是kafka不通，让你确认是不是安全协议的配置问题。你确认一下有没有用配置SSL，还有就是版本是否匹配。
