R is a free software environment for statistical computing and graphics that I’ve been using for a while for some specific tasks.

I wholeheartedly recommend the the awesome RStudio if you want to get to grips with it, and looking into RHadoop if you want to hook up with your Hadoop cluster (or, better still, SparkR)
