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. (was:

We can consider adding an overloaded constructor in {{AbstractConfig}} to only
retains its defined configs as in {{ConfigDef}}.)
