The Zookeeper discovery method config is incredibly simple, there are two settings and they are both required.
hosts (required):
A list of host strings. Each host string should include the hostname and port, separated by a colon (”:”).
path (required):
A string setting denoting the base path to use when looking up or reporting
on node availability. For example, a path of /lighthouse/services would
mean that any services available would be found at the path
/lighthouse/services/service_name.
Warning
Altering the “path” setting is doable, but should be avoided if at all
possible. Whatever provisioning method is used to update the
zookeeper.yaml file is almost certainly going to leave many nodes out of
sync at least for a time. A situation where nodes don’t agree on where to
look for each other is indistinguishable from a large network outage.
A simple example with a three-member zookeeper cluster and a base path:
discovery/zookeeper.yaml
hosts:
- "zk01:2181"
- "zk02:2181"
- "zk03:2181"
path: "/lighthouse/services"
