Ratandeep Ratti updated PIG-4459:
---------------------------------
Description:
I see that in UDFS VALUELIST/VALUESET we wrap every element in a tuple no
matter the type of element, which means that we may wrap a tuple inside a
tuple if the input map contains tuples as values. In our Pig loaders we
specifically do not do this, when converting to DataBags we do not wrap
elements in tuples which are tuple equivalents. I wondering if this is the
intended behavior or is it a bug?
