title: Cloudera 5.6 spark memoryFraction settings
body: <p>I have a CDH 5.6 cluster with 5.6 CDM (manager). I am not sure where I can set the memoryfaction settings of spark - </p>
  
  <pre><code>spark.storage.memoryFaction
  spark.shuffle.memoryFaction
  </code></pre>
  
  <p>to try different settings and see performance of my sample application.</p>
