Eric Newton commented on ACCUMULO-3132:
---------------------------------------
I'm not sure its worth the engineering to fix this: just clear out Fate, reservations and locks on upgrade.

> Project: Accumulo
> Issue Type: Bug
> Components: master
> Affects Versions: 1.5.0, 1.5.1, 1.6.0
> Reporter: Eric Newton

> Fate uses java serialization to save objects to zookeeper. If an upgrade is performed while a Fate transaction is running, the data stored in Fate may not deserialize in the upgraded software unless developers are very careful about the Repo's internals.
