Hadoop Solution: Missing Poker Card

For my reference for a quick start-up. I'm sure it'll be useful to someone else eventually lol

Creating Random Set of Missing Cards:

Run $ python3 Input/createCards.py

Make sure HADOOP_CLASSPATH is defined.

$ export HADOOP_CLASSPATH=$(hadoop classpath)

Make file system on hadoop.

$ hdfs dfs -mkdir /user

$ hdfs dfs -mkdir /user/jaime

$ hadoop fs -mkdir /user/jaime/poker /user/jaime/poker/input

Move input file into hadoop.

$ hadoop fs -put '/home/jaime/Desktop/Poker/Input/cards.txt' /user/jaime/poker/input

Don't make an output folder. Hadoop will make one.

in sbin, run:

$ start-all.sh

Compile .java file.

$ javac -classpath ${HADOOP_CLASSPATH} -d ./Classes/ Poker.java

Convert to .jar.

jar -cvf poker.jar -C Classes/ .

Run with Hadoop.

$ hadoop jar poker.jar Poker /user/jaime/poker/input /user/jaime/poker/output

Get Results:

$ hdfs dfs -cat /user/jaime/poker/output/*
