title: Apache Spark: SparkPi Example
body: <p>I'm trying to run the Spark Examples and I just don't understand what's going on.
  I used </p>
  
  <pre><code>MASTER=spark://Illidan:7077 ./bin/run-example SparkPi 10
  </code></pre>
  
  <p>which does start the process, but all I get is <strong>INFO</strong> Messages.</p>
  
  <p>So what is the "10" for?</p>
  
  <p>Can the INFO Messages be turned of?</p>
  
  <p>Where is the Output? Where is the calculated Pi? </p>
  
  <p>Can I start the example from the shell? Do I have to start it from the spark shell to see the prints or is it saved in some file I don't know of? </p>
  
  <p>I swear to God I have been going through the documentation a hundred times. I need some help.</p>
  
  <p>Hier is a small snippet of my terminal output. Thanks in advance. :D</p>
