> Map-reduce plan optimization phase of query planning in pig uses several
> visitors. Each of these visitors use custom code to identify patterns in
> physical plan to determine if the optimization should be applied. Having
> pattern match utility classes that works with physical plan will make writing
> new visitors easier.
