> PigPen has been found to be a usable feature. The underlying PIG
> functionality, ILLUSTRATE, however, has not been stable and complete. It also
> has unique access paths that are not shared by the mainstream PIG call
> paths, which makes it hard if not impossible to maintain as the PIG evolves
> along.
> The purpose of this work is to use the common access paths yet still follow
> the performance-sensitive criteria for ILLUSTRATE, complete support for as
> many logical operators as theoretically possible,
> plus algorithm polishes and bug fixes as necessary. Details can be found in
> http://wiki.apache.org/pig/PigIllustrate
> Pig-366 has been for the PigPen in general, and was used for the previous
> ILLUSTRATE work too. With this JIRA, the work on ILLUSTRATE will be separated.
> This JIRA also serves as an umbrella for existing issues in ILLUSTRATE.
> Specifically, PIG-502, PIG-903, PIG-1066 should all fold into this issue.
