I am using AWS Elasticsearch service. To implement proper security policies, we need to sign requests sent to elasticsearch. We are using **Java High Level REST Client** to query elasticsearch.

Is it possible to sign (by sign, I mean adding provided `Authorization` header with each request) requests made by **Java High Level REST Client** library? If so, how?  
Here is the maven repo I am using:

[https://mvnrepository.com/artifact/org.elasticsearch.client/elasticsearch-rest-high-level-client/6.2.2](https://mvnrepository.com/artifact/org.elasticsearch.client/elasticsearch-rest-high-level-client/6.2.2)

I think that this page [https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-low-usage-initialization.html#java-rest-low-usage-initialization](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-low-usage-initialization.html#java-rest-low-usage-initialization) says how to add a `BasicHeader`.

BTW did you look at [cloud.elastic.co](http://cloud.elastic.co) and [https://aws.amazon.com/marketplace/pp/B01N6YCISK](https://aws.amazon.com/marketplace/pp/B01N6YCISK) ?
