> Internal topic creation should go to controller
> -----------------------------------------------

> Key: KAFKA-9751
> URL: https://issues.apache.org/jira/browse/KAFKA-9751
> Project: Kafka
> Issue Type: Sub-task
> Reporter: Boyang Chen
> Priority: Major
>
> In current trunk, we are still going to use ZK for topic creation in the
> routing of FindCoordinatorRequest:
> val (partition, topicMetadata) =
> CoordinatorType.forId(findCoordinatorRequest.data.keyType) match {
> case CoordinatorType.GROUP =>
> val partition =
> groupCoordinator.partitionFor(findCoordinatorRequest.data.key)
> val metadata = getOrCreateInternalTopic(GROUP_METADATA_TOPIC_NAME,
> request.context.listenerName)
> (partition, metadata)
> Which should be migrated to controller handling
