This document discusses using the R programming language and RHadoop libraries to perform association rule mining on big data stored in Hadoop. It first provides background on big data, association rule mining, and integrating R with Hadoop using RHadoop. It then describes setting up an 8-node Hadoop cluster using Ambari and installing RHadoop libraries to enable R scripts to run MapReduce jobs on the cluster. The goal is to use R and RHadoop to analyze a training dataset and discover interesting association rules.
