> We should add an end-to-end test which verifies that we can upgrade Avro types by adding and removing fields. We can use the general purpose job (FLINK-8971) after it added Avro types for that.
> What should happen is
> # Start general purpose job
> # Take savpoint
> # Change Avro type to have different fields
> # Resume from savepoint
> Check for different state backends: RocksDB, FsStateBackend
