[Hadoop Source Code Reading] [0]-original intention and various resources

Original Intention

I have been amateur maintenance of a hadoop application, always want to watch the hadoop source code, mainly based on this blog (http://caibinbupt.iteye.com/blog/262412) clues to look down, if you have their own interest in the middle of the first open a look.

The principle is mainly to look at the Code, supplemented by reading other people's articles, but it does not carefully read each line of code, know what the code can do, and come back to view the problem in the future, at the same time, I will record the information I have seen, and I will not summarize it myself (it is a waste of time, but the reference documentation provides the url myself)

Copy the text directly from the notes, and the layout may not be so nice.

 

Ps: Read code version as hadoop-0.20.2-cdh3u0
