> Currently the {{AbstractConfig}}'s constructor accepts the passed property map as well as the {{ConfigDef}}, and maintains the original map as well as the parsed values together. Because of it, with hierarchical config passing like {{StreamsConfig}}, the underlying configs will takes all the key-value pairs when constructed and hence cause WARNING log output.
