[jira] [Created] (PIG-5389) Passing null to REPLACE udf preventing JIT optimization

Koji Noguchi created PIG-5389:
---------------------------------

             Summary: Passing null to REPLACE udf preventing JIT optimization
                 Key: PIG-5389
                 URL: https://issues.apache.org/jira/browse/PIG-5389
             Project: Pig
          Issue Type: Improvement
            Reporter: Koji Noguchi


Saw a case where runtime for tasks varied by 10 times for the same code, same input, and same node.  Turns out Java was indecisive on enabling JIT optimization for REPLACE/Matcher/regex call path due to repetitive NPE thrown from inside.
