> Key: HUDI-3640

> When upgrading from table version 2 to 3, the logic checks if the key
> generator class is provided by user config. We should still use default
> SimpleKeyGenerator if not provided, instead of throwing an error in the
> upgrade step.

> config: %s or %s",
> HoodieTableConfig.KEY_GENERATOR_CLASS_NAME,
