[jira] [Created] (ACCUMULO-2596) Document failure mode around persistent version upgrades

Sean Busbey created ACCUMULO-2596:
-------------------------------------

             Summary: Document failure mode around persistent version upgrades
                 Key: ACCUMULO-2596
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2596
             Project: Accumulo
          Issue Type: Task
          Components: docs, master
    Affects Versions: 1.5.1, 1.4.5, 1.6.0
            Reporter: Sean Busbey
            Priority: Minor
             Fix For: 1.5.2, 1.6.1, 1.7.0


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.
