title: Using pyspark to read json file directly from a website
body: <p>is it possible to use sqlContext to read a json file directly from a website?
  for instance I can read file as such:</p>
  
  <pre><code>myRDD = sqlContext.read.json("sample.json")
  </code></pre>
  
  <p>but get I an error when I try something like this: </p>
  
  <pre><code>myRDD = sqlContext.read.json("http://192.168.0.13:9200/sample.json")
  </code></pre>
  
  <p>I'm using Spark 1.4.1
  Thanks in advance!</p>
