Jose Armando Garcia Sancio reassigned KAFKA-8480:
-------------------------------------------------
Assignee: Jose Armando Garcia Sancio (was: Anna Povzner)
> Clients may fetch incomplete set of topic partitions during cluster startup
> ---------------------------------------------------------------------------
>
> Key: KAFKA-8480
> URL: https://issues.apache.org/jira/browse/KAFKA-8480
> Project: Kafka
> Issue Type: Bug
> Affects Versions: 2.2.1
> Reporter: Anna Povzner
> Assignee: Jose Armando Garcia Sancio
> Priority: Major
>
> KafkaConsumer#partitionsFor() or AdminClient#describeTopics() may return not
> all partitions for a given topic when the cluster is starting up (after
> cluster was down).
> The cause is controller, on becoming a controller, sending
> UpdateMetadataRequest for all partitions with at least one online replica,
> and then a separate UpdateMetadataRequest for all partitions with at least
> one offline replica. If client sends metadata request in between broker
> processing those two update metadata requests, clients will get incomplete
> set of partitions.
> Proposed fix: controller should send one UpdateMetadataRequest (containing
> all partitions) in ReplicaStateMachine#startup().
