> 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]
