目前是我要通过我的服务器连远程服务器的 kafka，我的服务器只作 producer，远程服务器把我的 ip 加入白名单了, 我用 telnet 也能通，可是用代码(python: ptkafka\kafka-python)就报这种错：

pykafka: 'Failed to connect newly created broker for ip:host'
kafka-python: 'NoBrokersAvailable'

目前是 broker 或者配置问题？另外我服务器不需要安装 kafka 了吧？

我才看了半天 kafka 菜鸡求教大佬们

后来加上api_version参数后就如下错误，找了好多说是kafka配置问题..
