Preparing the RHadoop environment
As RHadoop requires an R and Hadoop integrated environment, we must first prepare an environment with both R and Hadoop installed. Instead of building a new Hadoop system, we can use the Cloudera QuickStart VM (the VM is free), which contains a single node Apache Hadoop Cluster and R. In this recipe, we will demonstrate how to download the Cloudera QuickStart VM.
To use the Cloudera QuickStart VM, it is suggested that you should prepare a 64-bit guest OS with either VMWare or VirtualBox, or the KVM installed.
If you choose to use VMWare, you should prepare a player compatible with WorkStation 8.x or higher: Player 4.x or higher, ESXi 5.x or higher, or Fusion 4.x or higher.
