deserialize can return null if evalSpec is empty, need to extend the check on
the previous line to include setting evalPipe
String evalSpec = job.get("pig.combineFunc", "");
EvalSpec esp = (EvalSpec)ObjectSerializer.deserialize(evalSpec);
if(esp != null) esp.instantiateFunc(pigContext);
evalPipe = esp.setupPipe(finalout);
