Getting started with MapReduce/Hadoop

Question

Hi,

Lately, i have reading a lot about MapReduce/Hadoop and think this is where industry is currently moving to. I want to start learning MapReduce/Hadoop and i thought the best way to start would be to implement some small project. However, i tried to do some googling, but couldnt find anything.

Can you guys give me some links or may be some books that can give me a practical introduction to this technology. May be a small project that i can implement on my own to get a better understanding of the technology.

Thanks, Chander
