+1 I would actually go a step further and propose to remove both PDK and builtins. I've went through the code for both and here is what I found:
Builtins: - BuiltInUtils.java: Empty file - UDAFUnionMap: Merges maps. Doesn't seem to be useful by itself, but was intended as a building block for PDK PDK: - some helper build.xml/test setup + teardown scripts - Classes/annotations to help run unit tests - rot13 as an example >From what I can tell it's a fair assessment that it hasn't taken off, last commits to it seem to have happened more than 1.5 years ago.
