Everyone is saying that the world is going the cloud way. Big Data, Analytics etc are today’s buzzwords. I used to wonder what is so special about the cloud? I read a bit about Hadoop, HBase (the NoSQL DB for Hadoop) etc and came to know about the Map Reduce Framework.
Map Reduce is a framework which helps us to write program for the cloud. It is a simple framework. The MapReduce version of the Hello World program for Hadoop is the WordCount program.
I decided to start experimenting with this framework and have written a couple of programs. Find it here in my git repo.
