------------------------------------------
Hi [~shralex].
I have one question regarding backoff thing. I think it's better to do backoff
only when client need to move between servers. However, this should be done
before
{code}
if (reconfigMode) {
clientCnxnSocket.testableCloseSocket();
}
{code}
right?
I wonder how we could change updateServerList to support such callback? Any
idea?

> ZOOKEEPER-1355 introduced client-side rebalancing, which is implemented in
> both the C and Java client libraries. However, it requires the client to
> detect a configuration change and call updateServerList with the new
> connection string (see reconfig manual). It may be better if the client just
> indicates that he is interested in this feature when creating a ZK handle and
> we'll detect configuration changes and invoke updateServerList for him
> underneath the hood.
