      Description

      updateAccumuloVersion does a non-atomic update of the persisted version, and getPersistentVersion relies on the ordering of the underlying fs/Volume to determine which version to return.

      We should document what happens when there's a partial failure, improve reporting in it to the operator, and document how to fix it.
