Cluster is having 6 nodes, having the default role: cdfhilmrstw

How to update the node.roles from all to master only.  
Note: node has already a shards assigned, containing .security-7 index.

IF I run elasticsearch-node repurpose to delete data to be master eligible node, password for default elastic user was also getting deleted.

Goal is to update the nodes, with each specific roles e.g. 3 master, 2 data, and 1 ingest nodes.

Thanks

You can add **node.roles** to $ES\_HOME/config/elasticsearch.yml

Example:

- **node.roles:** _[master]_

For all roles or some, you can do

- **node.roles:** _[master, data, data\_hot, data\_warm, data\_cold, data\_frozen, data\_content, ingest, ml, remote\_cluster\_client, transform]_

Reference to all role names, you can use this [link](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-node.html#node-roles)
