Ron Dagostino updated KAFKA-10418:
----------------------------------
Description:
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.
