> The ZooKeeperPersistenceEngine contains information about concurrently
> existing Masters and Workers. This information, as the name suggests, is
> persistent in the event of a Master failure/restart. If the Spark version is
> upgraded, the Master will crash with a Java serialization exception when
> trying to re-read the persisted data.
> Instead of crashing (indefinitely), the Master should probably just ignore
> the prior data.
