As you suggested I did these changes to the server.properties file on all nodes.
log.retention.check.interval.ms=10000 log.retention.ms=10000 log.segment.bytes=10490000 How I start each server is by, /home/ubuntu/eranga/software/kafka_2.11-0.10.0.1/bin/kafka-server-start.sh -daemon /home/ubuntu/eranga/software/kafka_2.11-0.10.0.1/config/server.properties However, I still get about 4GB log files. Did I miss anything?
