amazon-web-services - 使用 whirr 启动集群

Question

我是 whirr 和 AWS 的新手，所以如果我问的问题很愚蠢，请提前致歉。

我遵循指示 here设置 whirr 和

bin/whirr launch-cluster --config hadoop.properties

失败并出现以下情况:

[~/src/cloudera/whirr-0.1.0+23]$ bin/whirr version                                                                                                                                       rvm:ruby-1.8.7-p299

我的 hadoop.properties 文件有一个 AWS 访问 key 和 secret 访问 key 。

关于我可能做错了什么以及我需要做什么来解决这个问题的任何指示？

谢谢!

Answer 1

好的，这似乎是我的 hadoop.properties 文件中的语法问题。在从 AWS 管理控制台复制我的 key 的过程中，“Whirr.credential”被截断为“Whirr.cred”。

经典的脸掌瞬间!

无论如何，将其保留下来，以便谷歌搜索此错误消息的任何人都知道去三次检查他们的 hadoop.properties 文件!
