title: Difference between DataFrame, Dataset, and RDD in Spark
body: <p>I'm just wondering what is the difference between an <code>RDD</code> and <code>DataFrame</code> <em>(Spark 2.0.0 DataFrame is a mere type alias for <code>Dataset[Row]</code>)</em> in Apache Spark? </p>
  
  <p>Can you convert one to the other?</p>
