Subject RE: From standalone ZK instance to 3 instances
Date Wed, 20 Nov 2013 14:30:02 GMT
As you mentioned earlier, you are upgrading single instance to ensemble having size 3.

Could you tell me the all the three servers are fine. One has become LEADER and other two
in FOLLOWER state.

If server is running fine, could you check the zk server logs for the client session establishment,
it will give more information like:

2013-11-19 12:35:14,780 [myid:1] - INFO  [NIOServerCxn.Factory:/10.18.40.137:25000:ZooKeeperServer@868]
- Client attempting to establish new session at /10.18.40.137:53318

Thank you, Rakesh!

Yes, zk seems to have started corectly.

$ sudo ./zkServer.sh start zoo.cfg
JMX enabled by default
Using config: /opt/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
$

I tried
./zkCli.sh -server zk1:9983
and here's the output:
