Question

Write a python code to print (any given file) file as a csv format by using MRJob only. code must be able to run stand-alone MRJob application.

For submission to your work: Your final hand should be a single file name BDM.py that takes exactly one arguments for the input path. output will be handled through redirection.

Sample run: python BDM.py sample.csv > output.csv

Answer 1

First of all to using the MRJob, You will have to install MRJob. To install MRJob, You must have pip3 installed (If you already installed, you can skip this). To install use - pip3 install mrjob

from mrjob.job import MRJob
class BDM(MRJob):

    def converter(self, _, line):
        id, address = line.split(',')
      
        //extract anything from the input.csv
        //add it here and yield/print it
        
        yield id, temporary 

if __name__ == '__main__':
     BDM.run()

Your CSV should look like this --->


1, "81 Gourav Sardana, Bengaluru, KR"
2, "44 Near semeston garden, New York, NY"

To run this, use the same format as you suggested in your question i.e python3 BDM.py input.csv >output.csv
