Cheolsoo Park updated PIG-3456:
-------------------------------
Attachment: PIG-3456-1-no-whitespace.patch
Looks like a good clean-up to me. I am uploading the no-whitespace patch incase
someone else wants to take a look at it.
+1 assuming all the tests pass. Thank you Rohini for doing this!
> Reduce threadlocal conf access in backend for each record

> Issue Type: Improvement
> Affects Versions: 0.11.1
> Reporter: Rohini Palaniswamy

> 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.
