> On this page, an example is given for Coalesce:
> {code}
> DEFINE EmptyBagToNullFields datafu.pig.util.Coalesce();
> data = FOREACH data GENERATE Coalesce(val,0) as result;
> {code}
> In this example, "EmpyBagToNullFields" should be replaced with "Coalesce", which is what
is used in the code following the define statement. My guess is this is a copy paste error
from an example further down when EmpyBagToNullFields is actually used.
