Hadoop Example Programs Source Code

I would like to analyze the map and reduce functions for some of the hadoop example programs (such as word count), but I am not sure where the source code is located. I have managed to google the source code for word count, but I believe it should be included somewhere in the hadoop package when I downloaded it.

Does anyone know where I can find the map and reduce functions for the hadoop example programs?
