Patrick Hunt commented on ZOOKEEPER-779:

I took a look at the patch, I don't see a big problem with this but I'm a 
little concerned about changing the semantics of zookeeper_init. Really I'd 
like to see us move to the strategy pattern directly rather than take a smaller 
step that ppl come to rely on and then we end up having to support (or break) 
going fwd. Qian I'm assuming this is working ok for you, but would you be 
interested in fleshing out the design of the strategy pattern and putting 
together a patch for that?

> In some scenario, whether the client can connect to zookeeper servers is used 
> as a logic condition. If the client cannot connect to the servers, the 
> program should turn to another fork. However, current zookeeper_init could 
> not tell whether the client can connect to one server or not. It could make 
> some users feel confused. I think we should check the connectivity to the 
> host in zookeeper_init, so we can tell whether the hosts are avaiable at that 
> time or not.
