KAFKA-4409; Fix deadlock between topic event handling and shutdown inâ¦
The consumer can deadlock on shutdown if a topic event fires during
shutdown. The shutdown acquires the rebalance lock and then the
topic-event-watcher lock. The topic event watcher acquires these in the reverse
order. Shutdown should not need to acquire the topic-event-watcherâs lock -
all it does is unsubscribes from topic events.
