Not able to set up zookeeper in replicated mode

Question

I am trying to set up zookeeper in replicated node with 3 server.

my config file is like this

tickTime=2000 
dataDir=/var/lib/zookeeper/ 
clientPort=2181
initLimit=5
syncLimit=2
server.1=zoo1:2888:3888
server.2=zoo2:2888:3888
server.3=zoo3:2888:3888

I am getting following exception

Here is a quick checklist:

• Do you have a /var/lib/zookeeper/myid file?
• Are ids defined in that file in sync with machine names/IPs defined in config (zoo1 having id 1, etc...)?
