> When removing a peer, the client side will delete peerId under peersZNode
> node; then alive region servers will be notified and delete corresponding
> hlog queues under its rsZNode of replication. However, if there are failed
> servers whose hlog queues have not been transferred by alive servers(this
> likely happens if setting a big value to "replication.sleep.before.failover"
> and lots of region servers restarted), these hlog queues won't be deleted
> after the peer is removed. I think remove_peer should guarantee all
> corresponding zk nodes have been removed after it completes; otherwise, if we
> create a new peer with the same peerId with the removed one, there might be
> unexpected data to be replicated.
