Can you check your `node.processors` setting? It seems to be invalid.

Hi Vijay, it doesn't look possible to update `node.processors` using an API. According to the documentation:
> Thread pool settings are [static](https://www.elastic.co/guide/en/elasticsearch/reference/current/settings.html#static-cluster-setting) and can be changed by editing `elasticsearch.yml`

Yup, @tsullivan that's what I am looking for I want to update that using API due to My elastic servers running as containers after updating elasticsearh.yml file need to restart containers after restarting the elastic servers not working properly due to it troughing cluster not healthy unable to determine cluster health and data node saying this node already part of another cluster and unable to up that data node.

You should check out the documentation of how to restart an Elasticsearch cluster: [Full-cluster restart and rolling restart | Elasticsearch Guide [8.11] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/restart-cluster.html)
This will be the only option since there is no API or way of dynamically changing the setting you want to change.
