> Key: KAFKA-9254
> URL: https://issues.apache.org/jira/browse/KAFKA-9254
> Project: Kafka
> Issue Type: Bug
> Components: config, log, replication
> Affects Versions: 2.0.1
> Reporter: fenghong
> Priority: Critical
>
> We are engineers at Huobi and now encounter Kafka BUG
> Modifying DynamicBrokerConfig more than 2 times will invalidate the topic
> level unrelated configuration
> The bug reproduction method as follows：
> # Set Kafka Broker config server.properties min.insync.replicas=3
> # Create topic test-1 and set topic‘s level config min.insync.replicas=2
> # Dynamically modify the configuration twice as shown below
> {code:java}
> bin/kafka-configs.sh --bootstrap-server xxx:9092 --entity-type brokers
> --entity-default --alter --add-config log.message.timestamp.type=LogAppendTime
> bin/kafka-configs.sh --bootstrap-server xxx:9092 --entity-type brokers
> --entity-default --alter --add-config log.retention.ms=604800000
> {code}
> # stop a Kafka Server and found the Exception as shown below
> org.apache.kafka.common.errors.NotEnoughReplicasException: Number of insync
> replicas for partition test-1-0 is [2], below required minimum [3]
