>
> Probably PIG-3419 changed the order of the call such that now 'explain' is  
> showing the logicalPlan before the LogicalPlanOptimizer.optimize() is being 
> called.
> Before we had 
> {noformat}
> 1030             PhysicalPlan pp = compilePp();
> 1031             currDAG.lp.explain(lps, format, verbose);
> {noformat}
> where  LogicalPlanOptimizer.optimize() was called from compilePp().
