             Summary: Handling legitimate NULL values
                 Key: PIG-2726
                 URL: https://issues.apache.org/jira/browse/PIG-2726

    Affects Versions: 0.11

Look into SQL/Oracle server for how they are handling legitimate NULL values in the input
while performing operations like roll-up, filtering etc. Current implementation outputs NULL
string which should be replaced by actual null value.
