> Project: Kafka
> Issue Type: Bug

> Affects Versions: 3.7.0
> Reporter: HanXu
> Assignee: HanXu
> Priority: Blocker
> Fix For: 3.8.0, 3.7.1
>
> Original Estimate: 6h
> Remaining Estimate: 6h
>
> How to reproduce:
> 1. Launch a 3.4.0 controller and a 3.4.0 broker(BrokerA) in Kraft mode;
> 2. Create a topic with 1 partition;
> 3. Launch a 3.4.0 broker(Broker B) in Kraft mode and reassign the step 2
> partition to Broker B;
> 4. Upgrade Broker B to 3.7.0;
> The Broker B will keep log the following error:
> {code:java}
> [2024-04-18 14:46:54,144] ERROR Encountered metadata loading fault: Unhandled
> error initializing new publishers
> (org.apache.kafka.server.fault.LoggingFaultHandler)
> org.apache.kafka.image.writer.UnwritableMetadataException: Metadata has been
> lost because the following could not be represented in metadata version
> 3.4-IV0: the directory assignment state of one or more replicas

> Bug:
> - When reassigning partition, PartitionRegistration#merge will set the new
> replicas with UNASSIGNED directory;
> - But in metadata version 3.4.0 PartitionRegistration#toRecord only allows
> MIGRATING directory；
> {code:java}
> if (options.metadataVersion().isDirectoryAssignmentSupported()) {
> record.setDirectories(Uuid.toList(directories));
> } else {
> for (Uuid directory : directories) {
> if (!DirectoryId.MIGRATING.equals(directory)) {
> options.handleLoss("the directory assignment state of one
> or more replicas");
> break;
> }
> }
> }
> {code}
> Solution:
> - PartitionRegistration#toRecord allows both MIGRATING and UNASSIGNED
