title: using PIG to load a file
body: <p>I am very new to PIG and I am having what feels like a very basic problem. 
  I have a line of code that reads: </p>
  
  <pre><code>A = load 'Sites/trial_clustering/shortdocs/*'
        AS (word1:chararray, word2:chararray, word3:chararray, word4:chararray);
  </code></pre>
  
  <p>where each file is basically a line of 4 comma separated words. However PIG is not splitting this into the 4 words. When I do dump <code>A</code>, I get: <code>(Money, coins, loans, debt,,,)</code>
  I have tried googling and I cannot seem to find what format my file needs to be in so that PIG will interpret it properly. Please help!</p>
