------------------------------------
Summary: AbstractConfig to only retain defined ConfigDef when
parsing property map
Key: KAFKA-3786
URL: https://issues.apache.org/jira/browse/KAFKA-3786
Project: Kafka
Issue Type: Bug
Reporter: Guozhang Wang
Assignee: Guozhang Wang
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 another static constructor in {{AbstractConfig}} to only
retains its defined configs as in {{ConfigDef}}.
