@InterfaceStability.Evolving
public abstract class AdminClient
extends Object
implements AutoCloseable

The administrative client for Kafka, which supports managing and inspecting topics, brokers, configurations and ACLs. The minimum broker version required is 0.10.0.0. Methods with stricter requirements will specify the minimum broker version required. This client was introduced in 0.11.0.0 and the API is still evolving. We will try to evolve the API in a compatible manner, but we reserve the right to make breaking changes in minor releases, if necessary. We will update the InterfaceStability annotation and this notice once the API is considered stable.

                                                CreateTopicsOptions options)

Create a batch of new topics. This operation is not transactional so it may succeed for some topics while fail for others. It may take several seconds after CreateTopicsResult returns success for all the brokers to become aware that the topics have been created. During this time, listTopics() and describeTopics(Collection) may not return information about the new topics. This operation is supported by brokers with version 0.10.1.0 or higher. The validateOnly option is supported from version 0.10.2.0.

electPreferredLeaders

public ElectPreferredLeadersResult electPreferredLeaders(Collection<TopicPartition> partitions)

Elect the preferred broker of the given partitions as leader, or elect the preferred broker for all partitions as leader if the argument to partitions is null. This is a convenience method for electPreferredLeaders(Collection, ElectPreferredLeadersOptions) with default options. See the overload for more details.

Parameters:

electPreferredLeaders

public abstract ElectPreferredLeadersResult electPreferredLeaders(Collection<TopicPartition> partitions,
                                                                  ElectPreferredLeadersOptions options)

Elect the preferred broker of the given partitions as leader, or elect the preferred broker for all partitions as leader if the argument to partitions is null. This operation is not transactional so it may succeed for some partitions while fail for others. It may take several seconds after this method returns success for all the brokers in the cluster to become aware that the partitions have new leaders. During this time, describeTopics(Collection) may not return information about the partitions' new leaders. This operation is supported by brokers with version 2.2.0 or higher.

The following exceptions can be anticipated when calling get() on the futures obtained from the returned ElectPreferredLeadersResult:

• ClusterAuthorizationException if the authenticated user didn't have alter access to the cluster.
• UnknownTopicOrPartitionException if the topic or partition did not exist within the cluster.
• InvalidTopicException if the topic was already queued for deletion.
• NotControllerException if the request was sent to a broker that was not the controller for the cluster.
• TimeoutException if the request timed out before the election was complete.
• LeaderNotAvailableException if the preferred leader was not alive or not in the ISR.

Parameters:

partitions - The partitions for which the preferred leader should be elected.

options - The options to use when electing the preferred leaders.

Returns:

The ElectPreferredLeadersResult.
