"kafka.zookeeper.ZooKeeperClientTimeoutException:等待连接超时"仅在上市主题期间 [英] "kafka.zookeeper.ZooKeeperClientTimeoutException: Timed out waiting for connection" ONLY DURING LISTING TOPICS

问题描述

我发现了几个主题相似但上下文不同的问题:我可以连接以创建主题，但是无法列出主题，因为遇到了下面提到的错误(据我所知，人们面临基本问题.我只是为了列出主题列表而连接).

I found few questions with similar topic but different context: I can connect to create a Topic but I can't list the topics because I got the error mentioned below (as far as I could see, people were facing issues for basic connecting while I am getting only for listing the topic list).

万一重要，这是我的 docker-compose.yml :

version: "3"
services:
    zookeeper:
        image: wurstmeister/zookeeper

    kafka:
        image: wurstmeister/kafka
        ports:
            - "9092:9092"
        environment:
            KAFKA_ADVERTISED_HOST_NAME: "localhost"
            KAFKA_ZOOKEEPER_CONNECT: "zookeeper:2181"

我的控制台:

bash-4.4# kafka-topics.sh --create --zookeeper zookeeper:2181 --replication-factor 1 --partitions 1 --topic test2
Created topic test2.
bash-4.4# kafka-topics.sh --list --zookeeper localhost:2181

已编辑

将来的读者可能会很有用，我可以直接从Docker Kafka容器中列出所有主题，而无需登录Docker Zookeper容器( https://stackoverflow.com/a/56595227/4148175 )

C:\Users\>docker exec -it test1_kafka_1 bash

bash-4.4# kafka-topics.sh --list --bootstrap-server localhost:9092
__consumer_offsets
test2
test3
test_topic
bash-4.4# 

推荐答案

-zookeeper zookeeper:2181 似乎运行良好

-zookeeper本地主机:2181 总是会在kafka容器内失败，因为它没有运行Zookeeper服务器

--zookeeper localhost:2181 will always fail inside the kafka container because it's not running a zookeeper server

注意:最新的kafka版本支持使用-bootstrap-servers 代替，因此您可以从kafka容器中使用 kafka:9092 或 localhost:9092
