   I got a thought, there is a scenario that A leader can see its followers, but cannot see Zookeeper, and then the leader will be fenced when it attempts to shink isr or expand isr because it holds the leaderIsrUpdateLock, but now the leader can't be fenced because it just sends the message and will process message normally.
