> Key: KAFKA-9218

> Project: Kafka
> Issue Type: Bug
> Reporter: Mickael Maison

> Priority: Major
>
> MirrorSourceConnector.refreshTopicPartitions() does not handle topic creation
> failure correctly.
> If createTopicPartitions() fails to create a topic, the next time
> refreshTopicPartitions() it will not retry the creation. The creation will
> only be retried if another topic has been created in the source cluster. This
> is because knownTopicPartitions is updated before the topic creation is
> attempted and it's only refreshed if a new topic appears.
