I use tsv as input instead of csv. To convert csv to tsv

CONVERT

python convert.py < songs_normalize.csv > songs_normalize.tsv
or
python3 convert.py < songs_normalize.csv > songs_normalize.tsv

compiling is as same as stated in pdf

COMPILE

hadoop com.sun.tools.javac.Main ∗.java
jar cf Hw3. jar ∗. class

Running is a little different.

Firstly, use songs_normalize.tsv generated from above instead of songs_normalize.csv

Secondly, remove Hw3 from the run command stated in the pdf

RUN

	hadoop jar Hw3.jar Total <tsv file path in hfs> output_total/
        hadoop jar Hw3.jar Average <tsv file path in hfs> output_average/
        hadoop jar Hw3.jar Popular <tsv file path in hfs> output_popular/
        hadoop jar Hw3.jar ExplicitlyPopular <tsv file path in hfs> output_explicitlypopular/
        hadoop jar Hw3.jar DanceByYear <tsv file path in hfs> output_dancebyyear/
