An odd number of servers is recommended because you don't gain anything
from having one more (making it an even number).
https://zookeeper.apache.org/doc/r3.6.1/zookeeperAdmin.html#sc_CrossMachineRequirements
Relevant info on that page:

For the ZooKeeper service to be active, there must be a majority of
non-failing machines that can communicate with each other. To create a
deployment that can tolerate the failure of F machines, you should count
on deploying 2xF+1 machines. Thus, a deployment that consists of three
machines can handle one failure, and a deployment of five machines can
handle two failures. Note that a deployment of six machines can only
handle two failures since three machines is not a majority. For this
reason, ZooKeeper deployments are usually made up of an odd number of
machines.

I could not figure out what your second email was asking. Subject:
