apache-kafka - Zookeeper 错误 : dataDir is not set

Question

我正在使用 kafka 快速入门教程来设置生产者-消费者连接。
https://kafka.apache.org/quickstart

我一直在使用本教程一段时间，直到现在它都运行良好。
当我运行动物园管理员时:

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

我收到以下错误:

[2017-01-14 18:57:18,148] INFO Reading configuration from: config/server.properties (org.apache.zookeeper.server.quorum.QuorumPeerConfig)
[2017-01-14 18:57:18,159] ERROR Invalid config, exiting abnormally (org.apache.zookeeper.server.quorum.QuorumPeerMain)

Invalid config, exiting abnormally

这是在手动杀死一些尾部进程之后发生的。我怎样才能克服这个错误？我已经下载了一个新的 kafka quickstart 文件夹，但错误仍然存​​在。我的 zookeeper.config 文件:

...

dataDir=/tmp/zookeeper
# the port at which the clients will connect
clientPort=2181
# disable the per-ip limit on the number of connections since this is a non-production config
maxClientCnxns=0

谢谢!

您的启动命令显示 config/zookeeper.properties但您的错误消息引用了 config/server.properties .

Zookeeper 应该以 zookeeper.properties 启动和 Kafka 应该从 server.properties 开始.

不要把这些搞混，否则都不会开始
