Why R?Well, you can use R for pretty much anything in analytics these days. Besides allowing users to do data discovery, it also provides a myriad of packages for model building and predictive analytics.
Why Hadoop?I almost goest without saying. Hadoop is an amazing platform for processing predictive analytic models on top of Big Data.
Why PMML?PMML is really the glue between model building (say, R, SAS EM, IBM SPSS, KXEN, KNIME, Python scikit-learn, .... ) and the production system. With PMML, moving a model from the scientist's desktop to production (say, Hadoop, Cloud, in-database, ...) is straightforward. It boils down to this:
R -> PMML -> Hadoop
