changing kafka retention period during runtime

Question

With Kafka 0.8.1.1, how do I change the log retention time while it\'s running? The documentation says the property is log.retention.hours, but trying to change

Answer 1

I tested and used this command in kafka confluent V4.0.0 and apache kafka V 1.0.0 and 1.0.1

/opt/kafka/confluent-4.0.0/bin/kafka-configs --zookeeper XX.XX.XX.XX:2181 --entity-type topics --entity-name test --alter --add-config  retention.ms=55000

test is the topic name.

I think it works well in other versions too
