Santhosh Srinivasan commented on PIG-1014:

Another option is to change the implementation of COUNT to reflect the proposed 
semantics. If the underlying UDF is changed then the user should be notified 
via an information message. If the user checks the explain output then (s)he 
will notice COUNT_STAR and will be confused.

> Pig should convert COUNT(relation) to COUNT_STAR(relation) so that all 
> records are counted without considering nullness of the fields in the records
