• Perform the installation of RHadoop's rmr and rhdfs packages as in section 5.9.A.

• Run the examples on squaring the numbers 1 to 100, firstly using a simple R script, and, secondly using the MapReduce function of the RHadoop rmr package. In the console, observe the number of splits and the mapping and reducing processes.

• You will now perform Data Analysis using RHadoop
