> Notify listeners of raft client shutdowns
> -----------------------------------------

> Key: KAFKA-12982
> URL: https://issues.apache.org/jira/browse/KAFKA-12982
> Project: Kafka
> Issue Type: Sub-task
> Reporter: Jose Armando Garcia Sancio
> Assignee: HaiyuanZhao
> Priority: Major

> `RaftClient.Listener.beginShutdown` should be called when the `RaftClient` is
> shutting down. I think there should be two ways to terminate the
> `RaftClient`. Those are `shutdown` and `close`.
> It looks like the current code for `close` only closes the metrics registry.
> It doesn't notify the listeners that the raft client was close. It doesn't
> stop future `poll` from updating the raft client.
> There is also an assumption that `shutdown` can only be called once. I think
> to satisfy this we should remove this method from `RaftClient` and keep it as
> implementation method in `KafkaRaftClient`.
