[~huxi_2b] thanks for your reply ,this is the code of props ,

props.put("zookeeper.session.timeout.ms", "30000");
props.put("rebalance.max.retries", "10");
props.put("rebalance.backoff.ms", "3000");

consumer/ZookeeperConsumerConnector$ZKSessionExpireListener  handleNewSessi=
on never called,  when network recovered , it should be ?=20

> hey guys , I got this problem this days,
> because of the network is unstable=EF=BC=8C consumer rebalance failed aft=
er 5 times ,the log shows that zk path /consumers/$(groupIdName)/ids/ is em=
pty,
> consumer seems can't register after network recovered, so i got the kafka=
 source code (0.8.2.2) and found the consumer/ZookeeperConsumerConnector$ZK=
SessionExpireListener handleNewSession won't call , and handleStateChanged =
do nothing,
> so i change the code like this ,and it seems works ,  and i checked 0.10.=
0.0 version, the same problem, is this a bug ? i'm confused , thank you.
>   def handleStateChanged(state: KeeperState) {
>        // do nothing, since zkclient will do reconnect for us.
>          if(state=3D=3DKeeperState.SyncConnected){
>               handleNewSession()
>          }
>       System.err.println("----------------ZKSessionExpireListener--------=
---- handleStateChanged-----state:"+state+"----"+state.getIntValue)
>       }
