Zookeeper settings question - Help Needed

Hi

Can someone please tell me if I can use multi server setup config/zoo.cfg
with just 1 server or is it must to have more than 1 zk server for a multi
server setup ?

I have been unsuccessful so far trying to get a 1 node zookeeper server to
work. My settings are as follows as I don't have more servers at the moment.

tickTime=2000
dataDir=/var/lib/zookeeper/
clientPort=2181
initLimit=5
syncLimit=2
server.1=zoo1:2888:3888


Thanks.

Edit for my above reply, if dataDir is at /var/lib/zookeeper/ , then place
the myid file at /var/lib/zookeeper/myid and try to start zookeeper server.

@Raghav - Have u created inside the dataDir directory , a data directory
with file myid that contains the server id which in your case will be 1 as
you are specifying server.1 in the config file. So your dataDir structure
will contain a file at the path like /var/lib/zookeeper/data/myid which
will contain 1 as your server id. Give it a try.
