你好,胡夕老师,kafka_version=2.12.2.3.0,使用的授权方式是SASL_PLAINTEXT,在config/server.properties配置allow.everyone.if.no.acl.found=true,使用未设置权限的topic,发送消息,会有授权失败的日志。 日志如下: SocketServer brokerId=0] Failed authentication with /10.192.0.1 (Unexpected Kafka request of type METADATA during SASL handshake.) (org.apache.kafka.common.network.Selector)
