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. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
