@tamaashu Generally speaking I agree with you, but that directory is
somewhat different. There is code in it which we don't generate during our
build process, but it's been in git since the beginning of ZooKeeper.
I have no idea why that directory named 'generated'. It's quite misleading.
@afine @tamaashu please take a closer look before making a judgement.---
