通过以上步骤,可以逐步排查和解决“kafka broker may not be available”的问题。如果问题仍然存在,可能需要进一步检查Kafka的依赖服务(如Zookeeper)的状态和配置。
场景:安装完kafka集群后,程序创建topic时报错could not be established. Broker may not be available 问题: 1.kafka开放了9092,9093,9094这三个端口,使用语句 firewall-cmd --zone=public --add-port=80/tcp --add-port=8080/tcp --add-port=443/tcp --add-port=7000/tcp --add-port=3306/tcp --add...
一定要在 kafka 启动前再三确认每台服务器的zookeeper都是正常启动的 1. 问题 用spark 连接时出现: Broker may not be available [Consumer clientId=consumer-1, groupId=group_id1] Connection to node -3 could not be established. Broker may not be available. 参考 WARN NetworkClient: [Consumer clientI...
启动生产或消费时,如果报错:could not be established. Broker may not be available jps查看进程 应该有QuorumPeerMain 和 Kafka 两个进程,否则就是kafka没有正常启动 也有可能是server.properties文件配置问题
kafka调试中遇到could not be established. Broker may not be available. (org.apac 启动生产者命令: kafka-console-producer.bat --broker-list localhost:9092 --topic haha 1. 启动消费者: kafka-console-consumer.bat --bootstrap-server localhost:9092 --topic haha --from-beginning...
简介: kafka报错: (localhost/127.0.0.1:9092) could not be established. Broker may not be available.具体报错:[Producer clientId=console-producer] Connection to node -1 (localhost/127.0.0.1:9092) could not be established. Broker may not be available. (org.apache.kafka.clients.NetworkClient) 使用...
Connection to node 1 (localhost/127.0.0.1:9092) could not be established. Broker may not be available. 首先一点点来排查错误。 从错误信息可以看到,SpringBoot开启后连接的是127.0.0.1,也就是本地的Kafka broker,但是配置文件中配置的是服务器的IP地址。我本地也并没有安装Kafka和Zookeeper服务。
