Libo, Did you see this error in the broker 3's log, right after it was restarted? One of the reasons for this error is that the broker hasn't received the first LeaderAndIsr request from the controller yet. When a broker starts up, the only way it knows what partitions it owns is through the first LeaderAndIsr request. However, I think we can improve the log message to mention this. Do you mind filing a JIRA for this improvement?
Also, do you keep seeing this error or does the broker recover after some time?
