Hadoop Tutorial Part 1: Setting Up Your MapReduce Learning Playground

If you are talking large datasets, NoSQL, you definitely talk Map/Reduce and so Hadoop.

This is the first post of a series of small hadoop tutorials introducing progressively core hadoop functionnalities.

This first post is dedicated to build what I called a “MapReduce Learning Playground”: for practice or for a real need, you read or wrote on a sheet of paper the map and reduce functions that might solve a particular problem and you want to see it in action, not necessarily on huge data sets, just check that it computes the correct answer.
