Hello Friend,
    I am new in zookeeper. I am trying to install multiple zookeeper server
(cluster configuration on my own machin)
for that i have taken latest zookeeper release. (zookeeper-3.4.5.tar.gz) I
have extract this file in 3 multiple folders there as :
1) zookeeper-3.4.5
2) zookeeper-3.4.5.1
3) zookeeper-3.4.5.2
respectively and after that i have created data director for zookeeper using
(mkdir foldername) command. they are as
1) zookeeperdata1
2) zookeeperdata2
3) zookeeperdata3
respectively after that i have created myid file in each data directory with
id (1,2,3) respectively
my configuration files are

server 1 : zoo.cfg
tickTime=2000
initLimit=5
syncLimit=2
dataDir=/home/hduser/zookeeperdata1
clientPort=2181
server.1=localhost:2888:3888
server.2=localhost:2889:3889
server.3=localhost:2890:3890

server 2 : zoo.cfg
tickTime=2000
initLimit=5
syncLimit=2
dataDir=/home/hduser/zookeeperdata2
clientPort=2181
server.1=localhost:2888:3888
server.2=localhost:2889:3889
server.3=localhost:2890:3890

server 3 : zoo.cfg
tickTime=2000
initLimit=5
syncLimit=2
dataDir=/home/hduser/zookeeperdata3
clientPort=2181
server.1=localhost:2888:3888
server.2=localhost:2889:3889
server.3=localhost:2890:3890

After that i an going to zookeeper-3.4.5 folder and execute following
command
hduser@sigehere-lp:~/zookeeper-3.4.5$ java -cp
zookeeper-3.4.5.jar:lib/slf4j-api-1.6.1.jar:lib/slf4j-log4j12-1.6.1.jar:lib/log4j-1.2.15.jar:conf
org.apache.zookeeper.server.quorum.QuorumPeerMain conf/zoo.cfg
I got follwoing error where i had done mistake can any know about this
error:

You need to start all three servers (or at least 2) in order for them
to communicate. Just starting one, it won't have anyone to talk to.

Also you are using the same client port for all 3 servers, that's fine
in distributed mode but if you run all three on the same host only 1
of the three will come up (the other two won't be able to bind on the
client port).

You might find an easier time of it using something like this to
generate the configs/startupscripts.

Good luck,
