Zookeeper client exception when executing any command in client
This is my configuration file:

    tickTime=2000
    initLimit=20
    syncLimit=5
    dataDir=./store/data
    clientPort=2181

    server.1=A:3181:4181
    server.2=B:3181:4181
    server.3=C:3181:4181
    server.4=D:3181:4181
    server.5=E:3181:4181

After this, I started all of the servers. Then I started client in one of
those nodes. It shows connected but as soon as I enter any command it threw
exception and stopped.
