> When a new node joins topology, it sends its marshaller mappings in a discovery join message.
> Additional validation should be implemented to make nodes with conflicting marshaller mappings be rejected from connecting to the cluster.
> Such procedure is already implemented for binary metadata. Marshaller mappings should be validated in a similar way.
