java - 无法在 Apache Kafka 中启动 Zookeeper 服务器

Question

我在 kafka_home/bin/windows(按照建议 here )。然后我遇到与 here 相同的问题，它建议从 kafka 主页启动该程序。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)

有人知道怎么解决吗？

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，然后从那里运行 zookeeper-server-start.bat，ZK 启动脚本将有效地寻找它的配置位于 bin/windows/config/zookeeper.properties，但不存在。

查看启动 ZK 启动脚本的正确命令的现有答案 ( Apache Kafka error on windows - Couldnot find or load main class QuorumPeerMain )，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
