What is the purpose of using hostname -i during Edge installation? What if I do not want to bind the installation with a particular FQDN during a crawl install?

During the installation we use "hostname -i" to get the IP of the instance and based on the same the UUID for that instance is generated. We add this UUID in zookeeper which is a central repository for all UUIDs.

Till the time the IP of the machine does not change we are good. As the UUID of a machine is dependent on IP and we retrieve the same by hostname command. If the IP is changed the UUID will not match and can result in errors.
