> Before {{FORK}} was introduced, {{ClsuterTopologyManagerImpl}} and {{LocalTopologyManagerImpl}} assumed that the coordinator would always reply to other members' requests. After the introduction of {{FORK}} we added some hacks to work around the fact that the coordinator may not yet have a {{ForkChannel}} with our ID running **yet**, but we still expect the {{FORK}} setup to be symmetric after a reasonable amount of time.
> Stopping a {{FORK}} and starting it back without restarting the underlying channel also doesn't work, because a {{FORK}} start/stop does not trigger a new view. When a node sends a request to the coordinator and receives back a {{CacheNotFoundResponse}}, it assumes that it will also receive a new view, but if the {{CacheNotFoundResponse}} was a consequence of stopping a single {{DefaultCacheManager}}/{{ForkChannel}}, that view will never arrive.
> We don't restart individual cache managers in our tests, but the spark connector test suite does it, and it sometimes fails because of it:
