Parsing JSON using JsonLoader
I am having hard time representing the below JSON in Pig. All I need is either a bag or a tuple of toppings.

      "Barbecue Sauce",

I've tried the below (and other variations) with no luck. Appreciate some help.

data = LOAD '/user/hue/data/toppings.json' USING JsonLoader('Toppings:bag{t:tuple(chararray)}');
DUMP data;
