org.apache.pig.newplan.optimizer.PlanOptimizer.optimize()
Run the optimizer. This method attempts to match each of the Rules against the plan. If a Rule matches, it then calls the check method of the associated Transformer to give the it a chance to check whether it really wants to do the optimization. If that returns true as well, then Transformer.transform is called. @throws FrontendException
