If so, I can remove this method (i.e. L168). But that means we have to explicitly write all setters if we want to copy a ClusterConfig to a brand new one. And I'm not sure why this is error-prone. Would be appreciate if you can share more 😃 . that is a good helper method but we could neglect this copy-all when adding new field to `ClusterConfig` :( -- This is an automated message from the Apache Git Service.
