Review request for pig.
Bugs: PIG-3456
https://issues.apache.org/jira/browse/PIG-3456
Repository: pig
Description
-------
1) DefaultTuple has a protected boolean isNull = false; which is never used.
Removing this gives ~3-5% improvement for big jobs
2) Config checking with ThreadLocal conf is repeatedly done for each record.
For eg: createDataBag in POCombinerPackage. But initialized only for first time
in other places like POPackage, POJoinPackage, etc.
