Hi Patrick, Thanks for guidance here , based on below I only have presently 1 zk node so if I provision 2 new VM and install same version of zookeeper on them should I start them as standalone zookeepers first and then make changes to there server config file?
Also what are the valid zk configs that I would need to add on these 2 new VM's zk server config file?
