kafka学习问题

查看topic列表报超时

报错如下：

Error while executing topic command : Timed out waiting for a node assignment. Call: listTopics
[2024-02-28 14:36:57,024] ERROR org.apache.kafka.common.errors.TimeoutException: Timed out waiting for a node assignment. Call: listTopics
 (kafka.admin.TopicCommand$)

解决方法：修改server.properties文件中的listeners

listeners=PLAINTEXT://ip:9092

停止kafka运行：

bin/kafka-server-stop.sh 

重新启动kafka：

bin/kafka-server-start.sh -daemon config/server.properties

再次查看topic列表，发现如下报错：

bin/kafka-topics.sh --bootstrap-server 192.168.15.187:9092 --list
 
#报错内容
[2024-02-28 14:57:22,420] WARN [AdminClient clientId=adminclient-1] Connection to node -1 (/192.168.15.187:9092) could not be established. Broker may not be available. (org.apache.kafka.clients.NetworkClient)

解决方法：修改server.properties文件中的advertised.listeners即可

advertised.listeners=PLAINTEXT://ip:9092
