> LAST_UPGRADABLE_LAYOUT_VERSION is currently -7, which corresponds to Hadoop
> 0.14. How about we bump it to -16, which corresponds to Hadoop 0.18?
> I don't think many people are using releases older than v0.18, and those who
> are probably want to upgrade to the latest stable release (v1.0). To upgrade
> to eg 0.23 they can still upgrade to v1.0 first and then upgrade again from
> there.
