Class PhyPlanSetter

java.lang.Object
  org.apache.pig.impl.plan.PlanVisitor<PhysicalOperator,PhysicalPlan>

          org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.PhyPlanSetter

public class PhyPlanSetter
extends PhyPlanVisitor

Sets the parent plan for all Physical Operators. Note: parentPlan is a bit of a misnomer. We actually want all the operators to point to the same plan - not necessarily the one they're a member of.
