title: Getting Name Value JSON in PIG
body: <p>Hi guys i just started doing pig, I was wondering if JsonLoader is capable of parsing all value inside json. </p>
  
  <p>for example:</p>
  
  <pre><code>{"food":"Tacos", "person":"Alice", "amount":3}
  </code></pre>
  
  <p>and i need to get "food" stored as a relation in chararray and "Tacos" which is the value of "food" to another relation.</p>
  
  <p>after reading many tutorial and documentation, i havent found a built in method to do so. </p>
  
  <p>does it mean that the only solution to this is through UDF? </p>
  
  <p>thanks a lot!</p>
