Hi Suman,

This should be related to hostname. You have used below

server.1=3Dhost1:3888:4888
server.2=3Dhost2:3888:4888
server.3=3Dhost3:3888:4888

try to use actual hostname (or IP address preferable). I am using following=
 in my Zookeeper and it is working fine.

server.1=3D10.20.5.129:2888:3888
server.2=3D10.20.5.194:2888:3888
server.3=3D10.20.5.195:2888:3888

Thanks,
