Kirk True updated KAFKA-17731:
------------------------------
Component/s: consumer
> Kafka consumer client sometimes elapses wait time for terminating telemetry
> push
> --------------------------------------------------------------------------------
>
> Key: KAFKA-17731
> URL: https://issues.apache.org/jira/browse/KAFKA-17731
> Project: Kafka
> Issue Type: Bug
> Components: clients, consumer
> Affects Versions: 3.7.0, 3.8.0, 3.7.1
> Reporter: Apoorv Mittal
> Assignee: Apoorv Mittal
> Priority: Blocker
> Fix For: 3.9.0, 3.7.2, 3.8.1
>
>
> ClientTelemetryReporter awaits on the timeout to send terminating telemetry
> push but sometimes the wait is elapsed. The condition occurs intermitently
> which can affect closing time of the consumer.
>
> {*}The issue can only be reproduced when consumer is closed just after
> creating i.e. instantiated Kafka Consumer and closed it{*}. When consumer is
> instantly closed then, then worker thread goes for {{timed_waiting}} state
> and expects last telemetry push request, which gets completed by background
> thread poll. But as the consumer is instantly closed, the heartbeat thread
> can't send the telemetry request, which makes the consumer close to wait for
> timeout.

> Debug logs:
