I am using Pig for the first time, and have found myself dealing with data that is a bag containing single element maps.
{ [a#1], [b#2], [c#3] }
I'd like to join all the maps, and flatten away the bag, but I can't seem
to figure out how.
The desired output would be:
[a#1, b#2, c#3]
How can I go about that transformation?
