title: Minimal kafka-spark consumer
body: <p>I have been looking for a minimal <code>kafka</code>-<code>spark</code> consumer example in scala and did not find one with the 'New Consumer Configs' (<a href="http://kafka.apache.org/documentation.html#newconsumerconfigs" rel="nofollow">http://kafka.apache.org/documentation.html#newconsumerconfigs</a>) - rather the old ones. 
  I have been looking through many sites and did not find an example featuring the required configuration settings. </p>
  
  <p>Would someone have such an example please? </p>
