Apache Pig

You are supposed to do online research and find out one case study where Apache Pig was used to solve a particular problem. I am expecting 4 page write-up. Please provide as much technical details as possible about solution through Apache Pig. Please draw technical diagrams to explain the solution. 

I am expecting maximum one page for business problem and 3 pages of technical solution. 

I want everyone to do research and provide their own write-up.

Please draw your own diagrams and don't go more than 4 pages in total.
