org.apache.pig.newplan.logical.rules.ColumnMapKeyPrune
This Rule prunes columns and map keys and set to loader. This rule depends on MapKeysPruneHelper to calculate what keys are required for a loader, and ColumnPruneHelper to calculate the required columns for a loader. Then it combines the map keys and columns info to set into the loader.
