      Description

      Currently the NameNode upgrade/rollback/finalize framework only supports local storage. With edits being stored in pluggable Journals, this could create certain difficulties - in particular, rollback wouldn't actually rollback the external storage to the old state.

      We should look at how to expose the right hooks to the external journal storage to snapshot/rollback/finalize.
