title: Pig on a single machine
body: <p>Imagine that i have a file with 100 MM of records, and I want to use pig to wrangle it. 
  I don't have a cluster, but I still want to use PIG for productivity reasons. Could I use PIG in a single machine or it will have a poor performance?</p>
  
  <p>Does Pig will simulate a MR job in a a single machine, or will use a self backend engine to execute the process?</p>
