    Description

      Pig expects certain things about LogicalPlan, and optimizer logic depends on those to be true. Could that verifies that these assumptions are true will help in catching issues early on.
      Some of the assumptions that should be checked -
      1. All schema have valid uid . (not -1).
      2. All fields in schema have distinct uid.
