Can a lost znode be recovered automatically? Say, in a 3 znodes Zookeeper cluster, the cluster get into a critical status if a znode is lost. If I bring that lost znode back into running, can it rejoin the quorum?
If it can, then that means my zookeeper cluster can run forever if I can somehow take care of my znodes (say, running a watchdog); if it can not, then that means my zookeeper cluster will need get restarted after a long period of time (because you will lose the total zookeeper cluster after losing two znodes -- and that can happen if there is not mechanism for znode to rejoin) Thanks, Sean
