> Handle directory failure timeout

> Key: KAFKA-15649
> URL: https://issues.apache.org/jira/browse/KAFKA-15649
> Project: Kafka
> Issue Type: Sub-task
> Reporter: Igor Soarez
> Priority: Minor
>
> If a broker with an offline log directory continues to fail to notify the
> controller of either:
> * the fact that the directory is offline; or
> * of any replica assignment into a failed directory
> then the controller will not check if a leadership change is required, and
> this may lead to partitions remaining indefinitely offline.
> KIP-858 proposes that the broker should shut down after a configurable
> timeout to force a leadership change. Alternatively, the broker could also
> request to be fenced, as long as there's a path for it to later become
> unfenced.
> While this unavailability is possible in theory, in practice it's not easy to
> entertain a scenario where a broker continues to appear as healthy before the
> controller, but fails to send this information. So it's not clear if this is
> a real problem.
