使用命令运行pubsub kafka连接时：
.binwindowsconnect-standalone.bat .etckafkaWorkerConfig.properties
.etckafkaconfigSink.properties .etckafkaconfigSource.properties
我得到此错误：

我正在经营当地的Kafka经纪人和当地的动物园管理员。关于如何解决此问题的任何帮助！
属性文件
因此，在尝试了各种修复后，我发现我正在为Localhost使用错误的端口号。Zookeeper使用了端口2181，而Kafka Server则使用端口9092。因此，我在WorkerConfig.properties中的原始属性是：
bootstrap.servers=localhost:2181
应该是
bootstrap.server=localhost:9092
因此，故事的寓意是要确保您在连接器属性文件中使用了正确的kafka服务器的端口和端口号，而我是workerconfig。这在这里显示。这似乎是常识，但是我在试图修复其他错误时更改了端口号，但在不知不觉中添加了另一个错误。因此，如果收到上述错误，请检查您的Bootstrap.server属性。
