Using NOT NULL in a Pig FILTER statement.

[Parth Sawant]

I'm trying to Filter some null fields in Pig using 'IS NOT NULL' . For some
reason the null data values persist.
For eg: the following filter on storing it's contents, contains null values
for ABC and PQR.

X = FILTER D BY (ABC IS NOT NULL) AND (ABC==1) AND (PQR==1) AND (PQR IS NOT
NULL) ;


Can someone help with this?

Thanks
