The following program uses Mapreduce Programming to calculate total number of odd and even numbers in a given dataset and calculate the sum of each.

• Use test.sh before running the program on hadoop in order to test for any faults.
• System does not require hadoop to run test.sh.
• Modify input.txt as per your desire.

After starting the hadoop and copying the files into hdfs, following command(s) can be used to run the script

hadoop jar {hadoop-stream-3.x.x.jar_location} -file {mapper_file_location} -mapper mapper.py -file {reduer_file_location} -reducer reducer.py -input {input_file_location_hdfs} -output {output_folder_location_hdfs}
