Just modify the logging level of the chatty class (chatty interaction). Since in your logs you see log entries originating from org.apache.kafka.clients.consumer.internals.Fetcher you can simply adjust the logging level for that logger by adding following line to log4j.properties:

log4j.logger.org.apache.kafka.clients.consumer.internals.Fetcher=WARN

... or any wider catching logger since these are name spaced:

# adjusting logging for entire Kafka
log4j.logger.org.apache.kafka=WARN

Hope this helps
