A simple MapReduce framework from Coursera's Introduction to Data Science with examples

While it implements the gist of the MapReduce model, this framework only executes on a single machine.

Inside data/ is a bunch of test data, and inside solution/ is the expected output

Run

python wordcount.py data/books.json    

to test the word count example.

python join.py data/records.json    

to execute the SQL relation join example. Expected output can be verified against join.json

... and so on.
