Designing algorithms for Map Reduce

Ricky Ho has a great post about designing algorithms for Map Reduce jobs.

So I want to write down my findings but then found the scope is too broad and also I haven't spent enough time to explore different problem domains. Finally, I realize that there is no way for me to completely cover what Map/Reduce can do in all areas, so I just dump out what I know at this moment

Algorithms that Ricky discusses:

• Map-Only
• Sorting
• Inverted Indexes
• Statistical Computation
• In-Mapper Combine
• SQL Model
• Data Joins
