title: Hive explain plan understanding
body: <p>Is there any proper resource from where we can understand explain plan generated by hive completely? I have tried searching it in the wiki but could not find a complete guide to understand it.
  Here is the wiki which briefly explains how explain plan works. But I need further information on how to infer the explain plan.
