在Ubuntu 12.04上安装Hadoop时遇到问题 [英] Problems with installing Hadoop on Ubuntu 12.04

问题描述

我刚刚建立了一个新的Ubuntu 12.04 VM（Virtualbox），并希望在其上测试Hadoop。我遵循本指南： http://hadoop.apache.org/docs/r0 .20.2 / quickstart.html

我认为我在Java安装和JAVA_HOME路径上做了错误...
现在/ hadoop总是返回找不到命令

哪里需要提取hadoop文件夹？

我需要在之前设置SSH吗？什么是SSHD？

安装正确java版本的命令是什么？

我有什么进入hadoop-env.sh文件？

谢谢！

解决方案

我使用了这个很棒的教程。
只有变化是我安装了默认的Java6 ...

Michael Noll设置Hadoop的教程

I just set up a new Ubuntu 12.04 VM (Virtualbox) and wanted to test Hadoop on it. I am following this guide: http://hadoop.apache.org/docs/r0.20.2/quickstart.html

I think I am doing something wrong with the java installation and the JAVA_HOME path... Right now bin/hadoop always just returns "command not found"

Where do I have to extract the hadoop folder?

Do I need to set up SSH before? What about SSHD?

What are the commands to install the correct java version?

What EXACTLY do I have to enter into the hadoop-env.sh file?

Thanks!

解决方案

I used this great tutorial. Only change was that I installed a default Java6...
