> Key: KAFKA-16190
> URL: https://issues.apache.org/jira/browse/KAFKA-16190
> Project: Kafka
> Issue Type: Sub-task
> Components: clients, consumer
> Reporter: Lianet Magrans
> Assignee: Quoc Phong Dang
> Priority: Critical
> Labels: client-transitions-issues, kip-848-client-support, newbie
> Fix For: 3.8.0
>
>
> The heartbeat request builder should make sure that all fields are sent in
> the heartbeat request when the consumer rejoins (currently the
> HeartbeatRequestManager request builder is reset on failure scenarios, which
> should cover the fence+rejoin sequence).
> Note that the existing HeartbeatRequestManagerTest.testHeartbeatState misses
> this exact case given that it does explicitly change the subscription when it
> gets fenced. We should ensure we test a consumer that keeps it same initial
> subscription when it rejoins after being fenced.
