BigData Analysis with Hadoop and R

Duration: 5 Days

Course Background

This advanced course explores the synergy that can be realised by combining R with Hadoop to implement powerful data analysis and visualisation applications. The course explores approaches involving implementing Map/Reduce modules in R and then using Hadoop's parallel processing Map/Reduce framework to process very large amounts of data. The course will explore RHadoop’s packages that allow R to interact with Hadoop’s Distributed File System (HDFS), make it possible to write and submit MapReduce jobs, and also to interact with HBase.

Course Prerequisites and Target Audience

This course is aimed at data scientists, statisticians, data architects, and engineers who are planning to process and analyze vast amounts of information using R and Hadoop. Attendees are expected to have a reasonable amount of R programming experience and to have a sound basic understanding of Hadoop and Map/Reduce.
