Hi, Deploying ECK and trying to configure a client/coordinating-only node. The node roles is configured to: `node.roles: []` As stated [here](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-node.html#coordinating-only-node). But the client node seem to have all the roles and shards are wrongfully created on those nodes: ![image](https://us1.discourse-cdn.com/elastic/original/3X/e/b/eb94b8f8d812955021413a89a47cf7b60f266799.png) Also tried to configure according to [this](https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-node-configuration.html): `node.roles: !!seq ""` But Harness, which we use for deployment, is indicating that this is invalid: > ClassCastException: org.yaml.snakeyaml.nodes.ScalarNode cannot be cast to org.yaml.snakeyaml.nodes.SequenceNode Please advise. ---

Update: was able to finally change the node roles using the deprecated settings: ```auto - name: client config: node.data: false node.ingest: false node.master: false node.ml: false ``` But this is deprecated settings. Can someone from Elastic please advise? (We are using 7.10.2) ---

Have a look at: [Node | Elasticsearch Guide [7.12] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-node.html#coordinating-node) From that I'd guess something like: ```auto - name: client config: node.roles: [] ``` Does this work? ---

Unfortunately does not work. ---

Unfortunately this is a known issue we haven't fully solved yet in ECK: [Coordinator nodes cannot be defined using node.roles · Issue #3718 · elastic/cloud-on-k8s · GitHub](https://github.com/elastic/cloud-on-k8s/issues/3718) It has to do with yaml syntax for nil vs. empty arrays... We added a workaround for it starting ECK 1.4.0, so we properly treat a `nil` node.roles as an empty slice. See [Coordinator nodes cannot be defined using node.roles · Issue #3718 · elastic/cloud-on-k8s · GitHub](https://github.com/elastic/cloud-on-k8s/issues/3718#issuecomment-823264281). tl;dr: starting ECK 1.4.0 you should be able to use `node.roles: []` I suspect you are using an earlier ECK version? ---

Look like we are using ECK 1.2.1 so that must be the problem as you had written. Many thanks! ---
