Alan Gates commented on PIG-1014:
---------------------------------
I think I agree with Santhosh here. While it may be unfortunate that our
syntax makes it difficult to match the rather strange semantics of COUNT(x) vs
COUNT(*) in SQL, I'm not sure trying to make a distinct between COUNT(A) and
COUNT(A.$0) is the right solution. This will not be obvious at all to users.
If anything, the right way to do this would be COUNT(A.*), but I'm not sure
even about that.
> Pig should convert COUNT(relation) to COUNT_STAR(relation) so that all
> records are counted without considering nullness of the fields in the records
