List of switchGroupByPlanOp() Examples

Examples of switchGroupByPlanOp()

org.apache.pig.impl.logicalLayer.LOCogroup.switchGroupByPlanOp()
This does switch the mapping oldOp -> List of inner plans to newOp -> List of inner plans which is useful when there is a structural change in LogicalPlan @param oldOp the old operator @param newOp the new operator
