> Project: Apache Ozone
> Issue Type: Improvement
> Reporter: Ethan Rose

> OM Prepare for upgrade will be a no-op once ZDU is supported. There may be
> leftover state in the DB and VERSION file indicating that the OM was put in
> prepare mode in the prior version. We should remove this state in an upgrade
> action tied to OM version 100 (ZDU support) which will run when the OM is
> finalized.
>
> Similarly, SCM will not longer have a finalization-in-progress marker in its
> DB. This should be completely cleared out by the old version when SCM
> finishes finalizing, but we can also add an upgrade action to ensure it is
> removed.
