Looking at the documentation [cat nodes API | Elasticsearch Guide [8.11] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/cat-nodes.html#:~:text=node.role%2C%20r%2C%20role%2C%20nodeRole) It appears that a "Hot" node should have roles `hd` ... but that's not true in real life. Is a hot node not a "data" node? Are 'data\_content' nodes not considered 'data' nodes?

Generally no, see [these docs](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-node.html#data-node):

> In a multi-tier deployment architecture, you use specialized data roles to assign data nodes to specific tiers: `data_content` ,`data_hot` , `data_warm` , `data_cold` , or `data_frozen` . A node can belong to multiple tiers, but a node that has one of the specialized data roles cannot have the generic `data` role.

No `data_content` is different from `data`. It's abbreviated as `s` (I forget why)
