尝试启动kafka服务器，启动zookeeper后，出现ERROR Invalid config，异常退出

Question

我正在尝试为项目设置 kafka 服务器。我正在遵循本指南 - https://kafka.apache.org/quickstart 。我运行 zookeper 成功了，但是当我尝试启动 kafka 服务器时，出现以下错误。我尝试了对配置属性的不同路径，但我得到了相同的消息。

bin\windows\zookeeper-server-start.bat C:\Users\Atanas0104\Documents\kafka_2.12-2.3.0\config\server.properties

Invalid config, exiting abnormally

这是错误信息

Answer 1

错误是你是运行 zookeeper-server-start.bat with kafka server .properties，你需要尝试使用kafka-server-start.bat 1) 首先转到 kafka 所在的文件夹并尝试这个

.\bin\windows\kafka-server-start.bat .\config\server.properties

Answer 2

我觉得你的 server.properties 不好，我下载了它，我遇到了同样的情况，我只改变了

的最后一行

group.initial.rebalance.delay.ms=0

至

initial.rebalance.delay.ms=0

它确实奏效了。
