Lately, i have reading a lot about MapReduce/Hadoop and think this is where industry is currently moving to.开发者_开发问答 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


Cloudera (releases a Hadoop distribution) has some fantastic online training videos as well as a virtual machine with everything setup and able to run through examples from the online free training http://www.cloudera.com/resources/?type=Training


The most common examples that get thrown around are creating an inverted index, and implementing grep.

If you're looking for more information:

A really friendly introduction can be found here. The original paper is here.

And what looks like some good example code to get you going is here.


Here are some nice articles/videos/tutorials on getting started with MapReduce.


Trying to parachute over Hadoop without understanding MapReduce can be painful. I think the easiest way to understand the hammer is to see a nail. :) I wrote a blog article (Intro to Parallel Processing with MapReduce) where I describe a common problem and show how to solve it with and without MapReduce. Then I go on to show how MapReduce makes it straightforward to distribute the work on a cluster.


I would also suggest some alternative learning approach like videos and lectures. Like on YouTube : (You can follow from this one to some more)
