Robert Kanter commented on OOZIE-2290:
--------------------------------------
I've seen this problem before. I agree that we should move the version update
to after the DDL tweaks.
This still doesn't necessarily fix issues where the upgrade runs into a problem
part-way, and you have a partially updated database. Simply running the db
upgrade tool again won't always work. Ideally, we'd make it so that if there's
an error, it rolls back the changes as well. Alternatively, if there's some
way of making it so that running the db upgrade tool again somehow resumes the
upgrade.
> Oozie db version update should happen after all DDL tweak.
