Jiangjie Qin, author of that PR, was pretty familiar with Kafka. I believe he has good reason to add that method, which uses `org.apache.kafka.common.Configurable.configure` instead of `org.apache.kafka.common.serialization.Deserializer.configure`. And I guess the reason is likely due to backward compatibility. -- This is an automated message from the Apache Git Service.
