如何从Apache Hadoop 1.2.1降级到0.20.2版本(How to downgrade from Apache Hadoop 1.2.1 to 0.20.2 version)

 我使用Cygwin在Windows 7上使用Apache Hadoop 1.2.1启动了POC。 
 

 相信我，它充满了错误。 最初我试图开始修复bug ....在建议的地方加入补丁。 
 

 但它现在是限制的，它给出了失败错误......权限问题......现在随时都可以。 
 

 我想了解降级到0.20.2的步骤或可能的简单方法 

I started my POC using Apache Hadoop 1.2.1 on Windows 7 using Cygwin.
 

Believe me it is full of bugs. Initially I tried to start fixing up bugs....incorporate patches as and where suggested. 
 

But it is limit now, it gives failure error...permissions issues...just anytime now.
 

I want to know about the steps or probably easy way out to downgrade to 0.20.2

最满意答案

 您提供的所有文件名均有效。 
 您必须为文件命名以表示其内容： 
 

 我可以从文件名中说些什么： 
 scripts.js - 所有脚本，未最小化 
 index.js - 仅用于索引文件的脚本。 
 style.css - 页面的所有样式 
 main.css - 将在页面上使用的主要样式集，缺少特定部分 
 base.css - 与main.css相同 
 

 您必须选择最适合的名称。 

All your provided file name is valid.
 You must name your file to represent it's content:
 

What can I say from file name:
 scripts.js - All scripts, not minimized
 index.js - Only scripts that will be used in index file.
 style.css - All styles for page
 main.css - Main set of styles that will be used on page, missing specific parts
 base.css - Same as main.css
 

You have to select name that fits best.
