---------------------------------
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.
