Hello everyone,  
We need some hints for a situation.

We have an Elasticsearch cluster with version 7.10 and we configure it for data nodes as follows.

```auto
node.master: false
node.data: true
node.ingest: true

```

However, when I look at the node details, I see that all other roles are active.

```auto
10.x.y.1 16 81 0 0.02 0.01 0.00 cdhilrstw - els-data-1
10.x.y.2 49 80 0 0.00 0.00 0.00 cdhilrstw - els-data-2
10.x.y.3 31 79 0 0.00 0.00 0.00 cdhilrstw - els-data-3

```

- Is it a problem if the features I don't use are turned on? For example `ml`
- Will this have any performance impact?

Thank you 🙏

Hi,

Believe the way you are using is deprecated and you should use the `node.roles` property:

For example:

```auto
node.roles: [data_cold]

```

Having all roles will impact your cluster as all nodes will do everything.
