Dynamic change of node configuration settings

I know there is an API to change cluster wide settings in a transient and persistent way. But I need to add a tag on a single node without restarting the node. To be more precise, in addition to introducing a new tag node.storage_type = value in > elasticsearch.yaml, I want to add it through the REST API. Otherwise, the restart of the cluster node by node takes too long.

The nodes info API is a read-only API and does not allow PUT requests. So, does anybody know any way how to solve it? I am on Elasticsearch 1.5.x.

There is no way to do this dynamically unfortunately.
I can't find a feature request for this either, which is odd, so please feel free to raise one! https://github.com/elastic/elasticsearch/issues
