> Noticed few things while browsing code
> 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.
