Stephan Ewen commented on FLINK-6662:
-------------------------------------
Are you trying to let a Flink 1.3 recover a pending Job from an earlier Flink
version via a high-availability setup?
That pattern is not supported - Framework version upgrades should go through
savepoints, and not through ZooKeeper.
A fair point is, though, that this should be reported as an explicit exception,
not simply a {{ClassNotFoundException}}.
