A MapReduce program that runs in Hadoop and does the following:

a) Searches for all of the following/provided tokens in the input text file: hackathon, Dec, Chicago, Java

b) It accepts a input file to be searched containing lines of the form: Date,Time,Name,Tweet

Here is the exact data to type into your input file:

   9-Dec-14,5:00PM,‏#Hackatopia,Tribeca Film Hackathon: Code As A New Language For Content Creators
   28-Oct-13,7:00PM,‏#NYCHadoop,Hadoop-NYC Strata/Hadoop World Meetup at AppNexus NYC
   31-Dec-14,3:00PM,‏#Hackatopia,Designers, Developers, Doers, don't miss this upcoming Chicago hackathon

c) The Mapper code will search for all of the tokens in the input file and creates <key, value> pairs.

d) The Reducer code will output the number of tweets that contained each token.

Using the example above, the output would be: (hackathon, 2) (Dec, 2) (Chicago, 1) (Java, 0)
