Whether the terminology for the Node type **Client Node** has been changed to **Coordinating node** starting from the 5.X version of the elasticsearch? I believe functionality-wise there is no change.

Yes, these days we refer to a node that does not hold data, is not master-eligible, not ingest enabled, and does not participate in cross-cluster search as "coordinating-only node". A precise definition is in the [docs](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/modules-node.html#coordinating-only-node). There is indeed no change in functionality from what was previously referred to as a "client-only node", however starting in 5.0 you have to disable ingest for a node to be coordinating-only, and starting in 5.3 you have to disable a node from executing cross-cluster search requests for a node to be coordinating-only. Precisely:

```auto
node.master: false
node.data: false
node.ingest: false
search.remote.connect: false

```

Thanks for the clarification.
