Hi Team,

 

Does anybody has the experience of adding or removing the zookeeper service without having to restart the warden on all nodes in the cluster.

 

I understand the need to run configure.sh and a restart of warden is required to pickup the new zookeepers, but what if the existing leader is untouched and only a follower is removed/added.

 

assuming there is a 3 node quorum.

Node1: leader

Node2: Follower

Node3: Follower --> removed

Node4: follower --> New added

 

ofcourse we will remove first and add new.

 

Appreciate your response.

 

Thanks,

Karthik
