I'm trying to add node to a running cluster. I've got this running elasticsearch cluster status by running

```auto
GET /_cluster/stats

```

i got the running cluster name is elasticsearch, and by following this [adding node to cluster](https://www.elastic.co/guide/en/elasticsearch/reference/current/add-elasticsearch-nodes.html) i've modified elasticsearch.yml into

```auto
cluster.name: elasticsearch
node.name: node-1
script.painless.regex.enabled: true

```

but seems nothing changes. are there any documentation about adding node into running cluster. Is it possible to do such this? Im running this poc because according to some articles online its hard to add node into a running cluster. Any responds or suggestions will be appreciated so much. Thank you
