What is an empty bag, empty tuple, and Null?


How to represent empty bag, empty tuple, and Null?


which operations will generate empty tuple, empty bag?


I have this confusion because I do not have clarity when to use datafu.pig.bags.NullToEmptyBag() and EmptyBagToNullFields functions?

Can someone give some example for my understanding
