獲取相關 ID 為 74 的元數據時出錯：{topicC=LEADER_NOT_AVAILABLE}

Question

Error while fetching metadata with correlation id 74 : {topicC=LEADER_NOT_AVAILABLE} 。

這是我的代碼：我在 docker 創建了一些容器，只使用 jdk 映像。

三個動物園管理員容器

zookeeper00 00， 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 ...

三個卡夫卡容器

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 ...

接着

docker exec -it kafka00 bash

我創建了一個主題，但是當我發送一些消息時，它Error while fetching metadata with correlation id 38 : {topicC=LEADER_NOT_AVAILABLE}

當我在java中發送消息時，它也會拋出同樣的錯誤。

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}

能否指出問題所在，謝謝！

我通過添加另一個端口監聽解決了這個問題。 這是我的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
