我可以在没有 root 访问权限的情况下使用 hadoop cloudera 吗?
有点二进制问题(好吧,不是完全) - 但想知道是否能够配置cloudera / hadoop在节点上运行而无需root shell访问节点计算机(尽管我可以设置ssh无密码登录)?
从他们的说明看来,需要 root 访问权限,但我发现一个 hadoop wiki 表明可能不需要 root 访问权限? http://wiki.apache.org/nutch/NutchHadoopTutorial
a bit of a binary question (okay, not excatly) - but was wondering if one is able to configure cloudera / hadoop to run at the nodes without root shell access to the node computers (although i can setup ssh passwordless login)?
appears from their instructions that root access is needed, at yet i found a hadoop wiki which suggest root access might not be needed ? http://wiki.apache.org/nutch/NutchHadoopTutorial

你可以,是的。您只需从源代码安装,而不是 RPM 或 DEB。访问 http://archive.cloudera.com/docs/ 并单击“Tarball”之一” 右上角的版本(CDH2 或 CDH3)。
获得 tarball 后,您必须创建一个 hadoop 用户,设置一些环境变量等。
我鼓励您在 Get Satisfaction 中向 Cloudera 提问,我们更有可能回答您的问题。

谢谢,祝你好运。
You can, yes. You'll just have to install from source instead of RPM or DEB. Visit http://archive.cloudera.com/docs/ and click on one of the "Tarball" releases (either CDH2 or CDH3) in the top-right corner.
Once you get the tarball, you'll have to create a hadoop user, set some environment variables, etc.
I encourage you to ask Cloudera questions in Get Satisfaction, where we're more likely to answer your questions.

Thanks, and good luck.
