title: Spark Reading Json
body: <p>I try to make the examples on <a href="http://spark.apache.org/docs/latest/sql-programming-guide.html#sql" rel="nofollow">http://spark.apache.org/docs/latest/sql-programming-guide.html#sql</a></p>
  
  <p>I tried this command on shell :</p>
  
  <pre><code>val df = sqlContext.read.json("examples/src/main/resources/people.json")
  </code></pre>
  
  <p>It gives an error : "no input paths specified in job"</p>
  
  <p>Why this problem happens ? How can I deal with it ?</p>
  
  <p>Thanks.</p>
