use of org.apache.kafka.common.Uuid in project kafka by apache.

the class UpdateMetadataRequestTest method testVersionLogic.

 * Verifies the logic we have in UpdateMetadataRequest to present a unified interface across the various versions
 * works correctly. For example, `UpdateMetadataPartitionState.topicName` is not serialiazed/deserialized in
 * recent versions, but we set it manually so that we can always present the ungrouped partition states
 * independently of the version.
