Greg Harris commented on KAFKA-9228:
------------------------------------
"Creating" in "Creating connector" means creating an instance of the class.
From your perspective, it really means "starting".
> Reconfigured converters and clients may not be propagated to connector tasks

> Key: KAFKA-9228
> URL: https://issues.apache.org/jira/browse/KAFKA-9228
> Project: Kafka
> Issue Type: Bug
> Components: connect
> Affects Versions: 2.3.0, 2.4.0, 2.3.1, 2.3.2
> Reporter: Chris Egerton
> Assignee: Chris Egerton
> Priority: Major
> Fix For: 3.8.0, 3.7.1
>
>
> If an existing connector is reconfigured but the only changes are to its
> converters and/or Kafka clients (enabled as of
> [KIP-458|https://cwiki.apache.org/confluence/display/KAFKA/KIP-458%3A+Connector+Client+Config+Override+Policy]),
> the changes will not propagate to its tasks unless the connector also
> generates task configs that differ from the existing task configs. Even after
> this point, if the connector tasks are reconfigured, they will still not pick
> up on the new converter and/or Kafka client configs.
> This is because the {{DistributedHerder}} only writes new task configurations
> to the connect config topic [if the connector-provided task configs differ
> from the task configs already in the config
> topic|https://github.com/apache/kafka/blob/e499c960e4f9cfc462f1a05a110d79ffa1c5b322/connect/runtime/src/main/java/org/apache/kafka/connect/runtime/distributed/DistributedHerder.java#L1285-L1332],
> and neither of those contain converter or Kafka client configs.
