The init script always requires the zookeeper service

[LionelCons]

The init script is created from:

# Provides:          <%- @service_name -%>
# Required-Start:    zookeeper
# Required-Stop:

So zookeeper is always required.

As contrast, the Systemd unit file uses the service_requires_zookeeper variable via:

<%- if @service_requires_zookeeper -%>
Wants=zookeeper.service
After=network.target syslog.target zookeeper.service
Requires=zookeeper.service
<%- else -%>
After=network.target syslog.target
<%- end -%>
