I prefer having the new optimizer as default. That way we can make sure
everyone migrates to the new code instead hiding that against a flag. Reverting
to old behavior should only happen if there bugs/corner cases.

Sure. This doesn't make any difference to me because I am going to explicitly
enable the new optimizer in the pig.properties file regardlessly. The reason
why I asked is I thought it would be nicer if early adopters (Twitter, Yahoo,
Netflix, etc) could stabilize it first before opening it to the community. Some
conner cases/bugs might surprise users who do not follow JIRAs. Does this make
sense?

> Current algorithm for Partition Filter pushdown identification fails in
