Resolution: Duplicate
> Review consumer leave group request best effort and response handling

> Key: KAFKA-15846
> URL: https://issues.apache.org/jira/browse/KAFKA-15846
> Project: Kafka
> Issue Type: Sub-task
> Components: clients, consumer
> Reporter: Lianet Magrans

> New consumer sends out a leave group request with a best effort approach.
> Transitions to LEAVING to indicate the HB manager that the request must be
> sent, but it does not do any response handling or retrying (note that the
> response is still handled as any other HB response). After the first HB
> manager poll iteration while on LEAVING, the consumer transitions into
> UNSUBSCRIBE (no matter if the request was actually sent out or not, ex, due
> to coordinator not known). Review if this is good enough as an effort to send
> the request, and consider effect of responses that may be received and
> processed when there are no longer relevant
