Project: Pig
Issue Type: Bug
Affects Versions: 0.8.0, 0.9.0
Reporter: Thejas M Nair
Fix For: 0.9.0
In following statement, the null gets translated to string constant. The
statement is invalid, and should result in an error.
{code}
fil = filter l by a != null; -- This does not give an error, the correct usage
is "a is not null"
fil = filter l by a != adsf; -- this does give an error message saying that
there is no column asdf
