[GitHub] [kafka] rondagostino opened a new pull request #9199: KAFKA-10418: alter topic configs via kafka-topics error text
rondagostino opened a new pull request #9199:
URL: https://github.com/apache/kafka/pull/9199
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.

JDK 11 build failure was a n infrastructure issue. JDK 8 test failure is an unrelated flaky test (`org.apache.kafka.streams.integration.EosIntegrationTest.shouldNotViolateEosIfOneTaskFailsWithState[exactly_once]`). JDK 14 build was clean.

Actually, it turns out that the ability to use `kafka-configs --bootstrap-server` was only added in 2.5. So this could be backported to 2.5 and 2.6 (not all the way back to 2.2 as originally stated).

Thanks, @rondagostino.
I think it's OK to just have in trunk for now. We already did a 2.6 release and this is not a critical fix, just a help text change. But if someone feels strongly I will backport.

Note that KIP-377 landed in 2.2 and explicitly stated in the new code that altering topic configurations via `kafka-topics` was deprecated – even using the `--zookeeper` flag (setting topic configs using `kafka-topics` when using `--create` to create a topic is supported and works with --bootstrap-server; it’s just altering/deleting topic configs that was deprecated via `--zookeeper` and that never worked/never will work via `--bootstrap-server`). Therefore, potentially, this could be backported as far back as 2.2.x.
