Step by step to build my first R Hadoop System

Step by step to build my first R Hadoop System by Yanchang Zhao.

From the post:

After reading documents and tutorials on MapReduce and Hadoop and playing with RHadoop for about 2 weeks, finally I have built my first R Hadoop system and successfully run some R examples on it. My experience and steps to achieve that are presented at http://www.rdatamining.com/tutorials/rhadoop. Hopefully it will make it easier to try RHadoop for R users who are new to Hadoop. Note that I tried this on Mac only and some steps might be different for Windows.

Before going through the complex steps, you may want to have a look what you can get with R and Hadoop. There is a video showing Wordcount MapReduce in R at http://www.youtube.com/watch?v=hSrW0Iwghtw.

Unfortunately, I can’t get the video sound to work.

On the other hand, the step by step instructions are quite helpful, even without the video.
