Guozhang Wang updated KAFKA-3786: --------------------------------- Description: 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. We can consider adding an overloaded constructor in {{AbstractConfig}} to only retains its defined configs as in {{ConfigDef}}. was: 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.
