WMR Exemplar: Flickster network data
Initial Publication Date: August 13, 2014
Summary
The purpose of this module is to teach students how to analyze networks and datasets distributed over multiple files using the Hadoop framework with the WebMapReduce (WMR) interface. It is assumed that students are already familiar with the basics of hadoop and CSInParallel's WMR interface.
The exercises in this module use a network of friendships on the social movie recommendation site Flixster. Students will use it to learn how to analyze networks and chain jobs. The module contains example code to try and then additional suggestions for analyses that students can perform.

Learning Goals
Given an example of a map-reduce computation that computes a clustering coefficient, students will be able to complete their own analyses of the data to answer different questions.
Context for Use
This example can be used after students have gained some familiarity with the map-reduce concept and have used WebMapReduce (WMR), such as completing the introductory WMR module from this collection.
