title: Load multiple files with PigLatin (Hadoop)
body: <p>I have a hdfs file list of csv files with same format. I need to be able to <code>LOAD</code> them with pig together. Eg:</p>
  
  <pre><code>/path/to/files/2013/01-01/qwe123.csv
  /path/to/files/2013/01-01/asd123.csv
  /path/to/files/2013/01-01/zxc321.csv
  /path/to/files/2013/01-02/ert435.csv
  /path/to/files/2013/01-02/fgh987.csv
  /path/to/files/2013/01-03/vbn764.csv
  </code></pre>
  
  <p>They can not be globed as their name is "random" hash and their directories might contain more csv files.</p>
