无效的配置,从Kafka教程启动zookeper时异常退出

Question

我正在按照本教程尝试设置kafka,

https://kafka.apache.org/quickstart

在zookeeper上做部件时我得到了这个错误.它当然与配置有关,但我不明白它的范围.

bin/zookeeper-server-start.sh config/server.properties

Answer 1

如果仔细观察,您会注意到启动Zookeeper的命令是:

bin/zookeeper-server-start.sh config/zookeeper.properties

使用该zookeeper.properties文件.

看起来您复制了命令以启动正在使用的Kafka server.properties.

Answer 2

我通过执行以下操作在 Windows 上修复了此问题。

确保指定完整路径。

首先，进入bin\windowskafka 安装文件夹：

C:\kafka_2.12-2.0.0\bin\windows

然后，运行以下命令：

.\zookeeper-server-start.bat C:\kafka_2.12-2.0.0\config\zookeeper.properties

完成后，您将看到以下输出：

[2020-07-06 20:25:13,703] INFO Server environment:user.dir=C:\kafka_2.12-2.0.0\bin\windows (org.apache.zookeeper.server.ZooKeeperServer)
