==== Nore roles
|
||||||
|
|
||||||
|
You can define the roles of a node by setting `node.roles`. If you don't
|
||||||
|
configure this setting, then the node has the following roles by default:
|
||||||
|
`master`, `data`, `ingest`, `transform`, `ml`.
|
||||||
|
|
||||||
|
If you set node.roles, the node is assigned only the roles you specify.
