Sijie Guo commented on BOOKKEEPER-133:
--------------------------------------
> b) ZkTopicManager#unregisterWithZookeeper shouldn't be needed
my point is to stop following requests sending to a hub server while it is
shutting down. so I add code to remove the znode first.
> I don't understand what the consume message is for?
currently auto consume is counter-based. suppose consume interval is 5. client
received and consumed 4 messages, but clients didn't tell hub server it
consumed 4 messages while it closes subscription. sending a consume message
while closing subscription is to reduce duplicated messages.
> Hub server should update subscription state to zookeeper when losing topic or
> shutting down
