Leader and Follower configuration in Zookeeper

I am wondering where in Zookeeper do I have to configure my follower and my leader? When I have this in my config file:

server.1=zoo1:2888:3888 server.2=zoo2:2888:3888 server.3=zoo3:2888:3888

Which one is the leader which are the followers? Or is this part of the leader election?

Yes, that is part of the internal leader election. Those servers decide amongst themselves who is going to lead/follow. – sourcedelica

Any server in a zookeeper can become the leader at any time. If the current leader goes down, or a majority of servers can't connect to it, a new leader will be elected.

The only exception is observers.
