Yan Zhou commented on PIG-1098:
-------------------------------

As this patch is purely for performance improvements, there is no new test case 
created. So Hudson's complain in that regard should be ignored.

> Many in-core performance optimization opportunities exist in zebra, such as 
> removal of redundant precautionary checks, use of better collection types to 
> reduce levels of indirection to the memory objects, changing of input splits 
> in ascending sizes to descending sizes. Observed protyped improvements are 
> around 10% wall clock time improvements.
