In https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-gateway.html, the docs say that these gateway settings must be set on all master nodes, but that they require a full cluster restart to take effect.
Say I have a cluster with:
- 3 master-only nodes
- some data-only nodes
- some ingest-only nodes
- some coordinator-only nodes
Can I just set these gateway settings on the 3 masters' elasticsearch.yml file and restart just the 3 masters?
Or do I need to specify it in every node's elasticsearch.yml file and restart every node?
