title: Spark & Scala: Read in CSV file as DataFrame / Dataset
body: <p>coming from the <code>R</code> world I want to import an .csv into Spark (v.1.6.1) using the Scala Shell (<code>./spark-shell</code>)</p>
  
  <p>My .csv has a header and looks like</p>
  
  <pre><code>"col1","col2","col3"
  1.4,"abc",91
  1.3,"def",105
  1.35,"gh1",104
  </code></pre>
  
  <p>Thanks.</p>
