-----------------------------------------

             Summary: SPRINTF should return NULL on any NULL input
                 Key: PIG-4038
                 URL: https://issues.apache.org/jira/browse/PIG-4038
             Project: Pig
          Issue Type: Bug
          Components: internal-udfs
            Reporter: Philip (flip) Kromer
            Priority: Minor


SPRINTF will currently interpolate the string 'null' if supplied with null 
arguments, which is "helpful but not help-ing". This patch makes it return null 
if any argument -- format or fodder -- is null.
