Cascading Sample Recommender

The goal for this project is to create a sample application in Cascading 2.7 which shows how to build a simple kind of social recommender.

More detailed background information and step-by-step documentation is provided at

Build Instructions

To generate an IntelliJ project use:

gradle ideaModule

To build the sample app from the command line use:

gradle clean jar

Before running this sample app, be sure to set your HADOOP_HOME environment variable and clear the output directory, then to run on a desktop/laptop with Apache Hadoop in standalone mode:

rm -rf output
yarn jar ./build/libs/recommender.jar data/en.stop data/tweets output/token output/similarity

To view the results:

more output/similarity/part-00000
