> Changing a topic config with the kafka-topics command while connecting to Kafka via --bootstrap-server (rather than connecting to ZooKeeper via --zookeeper) is not supported.  The desired functionality is available elsewhere, though: it is possible to change a topic config while connecting to Kafka rather than ZooKeeper via the kafka-configs command instead.  However, neither the kafka-topics error message received nor the kafka-topics help information itself indicates this other possibility.  For example:
> {{$ kafka-topics.sh --bootstrap-server localhost:9092 --alter --topic test --config flush.messages=12345
> Option combination "[bootstrap-server],[config]" can't be used with option "[alter]"
> }}
> {{$ kafka-topics.sh
> ...
> --config <String: name=value>            A topic configuration override for the topic being created or altered...It is supported only in combination with -- create if --bootstrap-server option is used.
> }}
> Rather than simply saying that what you want to do isn't available, it would be better to say also that you can do it with the kafka-configs command.
