** Just go to the file directory root, open in terminal, and run python master.py

Master:

• handles all I/O to and from 📁 file
• creates mapper and combiner classes for MapReduce Usage

Mapper:

• creates a list of tokenized words from an input file and stores these in an array with the assumption that its value is one
• DISCLAIMER: I tried using a dictionary here, but Python dictionaries require unique Keys. As such, the replicate words were being discounted in the dictionary initially in the map stage--hence the usage of an array

Combiner/Reducer:

• the combiner module adds the words from the array into a dictionary as a key and adds a value of 1
• if the word already exists as a key, then the value is (if following strict MapReduce theory) appended by another element of 1
• however, due to difficulty in manipulating arrays as a value for the key in the Combine step dictionary, I merged the combine step with the reduce step in the counting of the elements of the supposed array of 1s in the value of each key
