title: Error in running Spark in Intellij : "object apache is not a member of package org"
body: <p>I am running a Spark program on Intellij and getting the below error :
  "object apache is not a member of package org".</p>
  
  <p>I have used these import statement in the code :  </p>
  
  <pre><code>import org.apache.spark.SparkContext  
  import org.apache.spark.SparkContext._  
  import org.apache.spark.SparkConf
  </code></pre>
  
  <p>The above import statement is not running on sbt prompt too.
  The corresponding lib appears to be missing but I am not sure how to copy the same and at which path.</p>
