Lists all hosts in the cluster
Displays a list of hostnames corresponding to each node in the cluster. Each hostname is printed to stdout on its own line. The hostname may or may not contain a port number. If the port number is not a part of the hostname, then the port number is assumed to be 8091.
To get a list of hostnames for each node in the cluster run the following command:
$ couchbase-cli host-list -c 192.168.1.5:8091 --username Administrator \ --password password
cb1.mydomain.com:8091 cb2.mydomain.com:8091 cb3.mydomain.com:8091
