After this awesome MapReduce in simple terms presentation, now we can explain MapReduce to our boss (nb there’s a risk in that though as we might give him ideas):
The next day, You stand with a mike on the dias before 50,000 and proclaim. For a week, you will all be divided into many groups:
- The Mappers (tens of Thousands of people will be in this group)
- The Grouper (Assume just one guy for now)
- The Reducers( Around 10 of em.) and..
- The Master(That’s you).
Then you talk to each one of the groups.
