Package org.apache.pig.newplan

Added Classes
FilterExtractor.KeyState
PartitionFilterExtractor	This is a rewrite of {@code PColFilterExtractor} Extracts partition filters for interfaces implementing LoadMetaData
PredicatePushDownFilterExtractor	We traverse the expression plan bottom up and separate it into two plans - pushdownExprPlan plan that can be pushed down to the loader and - filterExprPlan remaining plan that needs to be evaluated by pig If the predicate is not removable then filterExprPlan will not have the pushdownExprPlan removed.

 

Changed Classes
BaseOperatorPlan
