无法在 Apache Kafka 中启动 Zookeeper 服务器

Question

我在kafka_home/bin/windows（如建议here）。然后我遇到了与这里相同的问题，它建议从 kafka home 启动程序。从 windows 文件夹启动时出现此错误：

INFO Reading configuration from: config/zookeeper.properties (org.apache.zookeeper.server.quorum.QuorumPeerConfig)
[2014-08-21 11:53:55,748] FATAL Invalid config, exiting abnormally (org.apache.zookeeper.server.quorum.QuorumPeerMain)

有谁知道如何解决这个问题？

Answer 1

配置文件的默认位置是用相对路径指定的，config/zookeeper.properties.

Kafka 的目录树看起来有点像这样：

bin/
  |
  +-- zookeeper-server-start.sh
  |
  +-- windows/
        |
        +-- zookeeper-server-start.bat
config/
  |
  +-- zookeeper.properties

因此，如果您确实在bin/windows/目录中，然后zookeeper-server-start.bat从那里运行，ZK 启动脚本将有效地查找其在 处的配置bin/windows/config/zookeeper.properties，而该配置并不存在。

查看现有答案（Windows 上的 Apache Kafka 错误 - 无法找到或加载主类 QuorumPeerMain）以获取启动 ZK 启动脚本的正确命令，其中示例命令行明确定义了在哪里可以找到配置文件：

$ cd bin/windows
$ zookeeper-server-start.bat ../../config/zookeeper.properties

# The below will NOT work (explanation is above)
$ cd bin/windows
$ zookeeper-server-start.bat
