Raul Gutierrez Segales commented on ZOOKEEPER-2016:
---------------------------------------------------

sounds useful to me. we have to do manual re-balancing of clients (i.e.: by 
injecting TCP RSTs) way too often. making this easy to use would be great,

> 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.
