Hi, Is it possible to use Java TransportClient when using AWS ElasticSearch instance and access token? Where can I find documentation for that, please? Thanks for any advice. ---

No but [cloud.elastic.co](http://cloud.elastic.co) which runs on AWS supports it. ---

I have my own AWS Elasticsearch instance. From Python I connect it using generated access token. Python package "elasticsearch==5.4.0" has support for it. I need to choose good Java solution. I successfully connected to local ES instance from both Java TransportClient and Java REST. But I don't know how to connect to AWS instance where using of access token is needed. ---

If you are running your own ES instance, what does "access token" mean? There is nothing like this in elasticsearch by default. Are you using x-pack to secure your elasticsearch instance? ---

Access token is used when connecting to AWS Elasticsearch instance only. When I connect to my local instance, no access token is used. I don't know which Java client should I use when connecting to AWS Elasticsearch instance. I don't use x-pack, because it's for elasticsearch installation. It's not my case. Thanks. ---

As far as I know, the AWS Elasticsearch service (if this is what you are using) does not support the transport protocol, which means that you will need to use a REST based Java client. The Python client works as it is REST based. ---

I think so too. But I can't find full documentation of Java REST API. It's not contained in org.elasticsearch javadoc: [https://www.javadoc.io/doc/org.elasticsearch/elasticsearch/5.4.3](https://www.javadoc.io/doc/org.elasticsearch/elasticsearch/5.4.3). Example of using with AWS is also missed here: [https://www.elastic.co/guide/en/elasticsearch/client/java-rest/5.4/\_example\_requests.html](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/5.4/_example_requests.html). ---

This is what the Java REST Client supports for authentication: [https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/\_basic\_authentication.html](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/_basic_authentication.html) It's fully compatible with [cloud.elastic.co](http://cloud.elastic.co). ---

I don't need connect to [cloud.elastic.co](http://cloud.elastic.co), but to Amazon Web Services Elasticsearch. ---

I hear you. If the official client does not work with whatever other non official provider, then you probably need to ask this provider for advices. I can tell you that this client works fine with: - Local instances - [cloud.elastic.co](http://cloud.elastic.co) instances - Own deployed instances on whatever cloud provider, such as AWS, GCP, Azure... And probably some others. May I suggest that you ask your question on AWS forums and eventually update this thread so others will know what is needed to be done? ---

Ok, I will try it. ---
