Error while fetching metadata with correlation id 74 : {topicC=LEADER_NOT_AVAILABLE}，当我向某个主题发送新闻时。
这是我的代码： 我在docker上创建了一些容器，只需使用jdk镜像即可。
zookeeper00，zookeeper01，zookeeper02
dataDir=/data/config
clientPort=2181
maxClientCnxns=0
syncLimit=5
server.1=zookeeper00:2888:3888
server.2=zookeeper01:2888:3888
server.3=zookeeper02:2888:3888
initLimit=10
docker run -d --name zookeeper00 --network andy --network-alias zookeeper00 -p 2181:2181 ...
kafka00，kafka01，kafka02
broker.id=0
listeners=PLAINTEXT://kafka00:9092
advertised.listeners=PLAINTEXT://database_host:9092
zookeeper.connect=zookeeper00:2181,zookeeper01:2181,zookeeper02:2181
我在Windows的hosts文件中添加了192.168.153.131 database_host。 192.168.153.131是我的centos IP
docker run -d --name kafka00 --network andy --network-alias kafka00 -p 9092:9092 ...
docker exec -it kafka00 bash
我创建了一个主题，但是当我发送一些消息时，它引发了Error while fetching metadata with correlation id 38 : {topicC=LEADER_NOT_AVAILABLE}

当我用Java发送消息时，它也会引发相同的错误。
final Properties p = new Properties();
p.put(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG,"DATABASE_HOST:9092,DATABASE_HOST:9093,DATABASE_HOST:9094");
p.put(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, StringSerializer.class);
p.put(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG,StringSerializer.class);
p.put(ProducerConfig.CLIENT_ID_CONFIG,"producer-aa-1");
p.put(ProducerConfig.ACKS_CONFIG,"all");
producer = new KafkaProducer<>(p);
producer.send(new ProducerRecord<>(topicName, "a04", "test-msg-a04"));
Sending metadata request (type=MetadataRequest, topics=topicC) to node DATABASE_HOST:9093 (id: -2 rack: null)
Error while fetching metadata with correlation id 4 : {topicC=LEADER_NOT_AVAILABLE}
能否请您指出问题，谢谢！
答案 0 :(得分：0)
我通过添加另一个端口侦听来解决该问题。这是我的 server.properties
broker.id=1
listener.security.protocol.map=INSIDE:PLAINTEXT,OUTSIDE:PLAINTEXT
advertised.listeners=INSIDE://kafka00:9092,OUTSIDE://database_host:19090
listeners=INSIDE://:9092,OUTSIDE://:19090
inter.broker.listener.name=INSIDE
zookeeper.connect=zookeeper00:2181,zookeeper01:2181,zookeeper02:2181
