BigData Analytics MapReduce

 Assignment # 2 is a research assignment.

We studied MapReduce in lecture # 3. You are supposed to do online research and find out one case study where MapReduce was used to solve a particular problem. I am expecting 4-5 page write-up. Please provide as much technical details as possible about solution through MapReduce. 

I am expecting maximum one page for business problem and 3 pages of technical solution. I am not looking for copy-paste from some website.

There are so many examples where MapReduce has solved complex business problems. Please use power point or Visio to draw technical diagrams to explain the solution.
