Using external zookeper with solr cloud

Question

I am trying to implement solrcloud.I foollowed doc from official resource https://cwiki.apache.org/confluence/display/solr/Getting+Started+with+SolrCloud .It works fine with embeded zookeper but it is recomended to use external zookeper. I insalled zookeper on my system created data dictionary zookeper on my home folder.I created sub folders named 1 and 2 and created myid file with text 1 and two respectively i each folder as mentioned in doc.I created config files for zookeper zoo.cnfg

clientPort=2181
initLimit=5
syncLimit=2
server.1=localhost:2879:3879
server.2=localhost:2888:3888

and zoo2.cnfg

initLimit=5
syncLimit=2
clientPort=2182
server.1=localhost:2878:3878
server.2=localhost:2888:3888

Next I run cd

bin/zkServer.sh start zoo.cfg
bin/zkServer.sh start zoo2.cfg

And its started sucessfully. next I run

bin/solr start -e cloud -z localhost:2181,localhost:2182 system ask me no of shards etc like in getting started i select port for node1 8990 and for node 2 8991. It gives error

Waiting to see Solr listening on port 8991 [/]  Still not seeing Solr listening on 8991 after 30 seconds!

Your Zookeeper ensemble must have an impair number of nodes : 1, 3, 5, etc...

If you want to test ZK clustering feature than you have to set up at least 3 ZK instances. In this case, don't forget :

To set correctly the ZK server id in the file myid, that must be created in the directory dataDir, referenced by your zoo.cfg.
Separate the dataDir and dataLogDir for each ZK instance.
