Zookeeper Ensemble does not respond to client?

Question

I am new to Zookeeper and was setting up Solr Cloud using Zookeeper Ensemble in my system, The problem comes when I try to run all the Zookeepers together, There are three Zookeeper running on three separate ports and point them to my Solr which is installed on Apache Tomcat Server. The Configuration files are as follows :-

zoo1.cfg

tickTime=2000
dataDir=/Users/prime/Desktop/Deployment Docs/Zookeeper/data
clientPort=2181
initLimit=5
syncLimit=2
server.1=localhost:8002:3888
server.2=localhost:8005:3889
server.3=localhost:8008:3890

zoo2.cfg

tickTime=2000
dataDir=/Users/prime/Desktop/Deployment Docs/Zookeeper/data
clientPort=2182
initLimit=5
syncLimit=2
server.1=localhost:8002:3888
server.2=localhost:8005:3889
server.3=localhost:8008:3890

zoo3.cfg

tickTime=2000
dataDir=/Users/prime/Desktop/Deployment Docs/Zookeeper/data
clientPort=2183
initLimit=5
syncLimit=2
server.1=localhost:8002:3888
server.2=localhost:8005:3889
server.3=localhost:8008:3890

After this when I try to connect the server at 2181. Using ./zkCli it gives me the following error :-

sh-3.2#./zkCli.sh

My question is what is going wrong and how to get rid of this. Since I am not able to rectify it anyways.

Answer 1

First of all you should have separate data directory for each zookeeper instance. Inside the data directory create a file called myid. In those file only write 1, 2 or 3 depending upon the server (e.g For server1 write 1). Please check here

Then start your zookeeper ensemble.
