org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.plans.POPackageAnnotator
This visitor visits the MRPlan and does the following for each MROper - visits the POPackage in the reduce plan and finds the corresponding POLocalRearrange(s) (either in the map plan of the same oper OR reduce plan of predecessor MROper). It then annotates the POPackage with information about which columns in the "value" are present in the "key" and will need to stitched in to the "value"

            SecondaryKeyOptimizer skOptimizer = new SecondaryKeyOptimizer(plan);
            skOptimizer.visit();
        }
        
        // optimize key - value handling in package
        POPackageAnnotator pkgAnnotator = new POPackageAnnotator(plan);
        pkgAnnotator.visit();
        
        // optimize joins
        LastInputStreamingOptimizer liso = 
            new MRCompiler.LastInputStreamingOptimizer(plan, lastInputChunkSize);
