Assignee: (was: Agam Brahma)
> Detect deleted log directory before becoming leader
> ---------------------------------------------------
>
> Key: KAFKA-9347
> URL: https://issues.apache.org/jira/browse/KAFKA-9347
> Project: Kafka
> Issue Type: Improvement
> Reporter: Jason Gustafson
> Priority: Major
> Labels: needs-discussion
>
> There is no protection currently if a broker has had its log directory
> deleted to prevent it from becoming the leader of a partition that it still
> remains in the ISR of. This scenario can happen when the last remaining
> replica in the ISR is shutdown. It will remain in the ISR and be eligible for
> leadership as soon as it starts up. It would be useful to either detect this
> case situation dynamically in order to force the user to do an unclean
> election or recover another broker. One option might be just to pass a flag
> on startup to specify that a broker should not be eligible for leadership.
