it could be a strange question, but i need to have an alias for the same host in the cluster, for example:
if i have a host with node.name: host1 I would like to have an alias for the same host like: "host1.fake.org" (the real name FQDN of host1 is not host1.fake.org but host1.real.org)
I'm not sure this is related to Elasticsearch and what is the real issue.
The node.name can be anything, it doesn't need to be the same as the host name, but you can only have one node.name.
If you want that your elasticsearch responds to requests for host1, host1.fake.org or host1.real.org this is unrelated to elasticsearch, it is a DNS issue that depends on your operating system.
