  Hi all,

  I'm reading the source code of Hive cbo (CalcaitePlanner), but I find it
 hard to follow.
 Listed below are some of the questions:
 1. What's the relationship between HepPlanner and HiveVolcanoPlanner?
 2. I don't have a clue about these concepts: clusters, traitDef and
 collectGarbage().

  Thanks for any help.
