Hi Flavio, Got that, from my view I think RestClusterClient might not be viewed as public API, and might be change between version, thus it might need to be careful when upgrading.

Usually I interface with REST API using auto generated clients (if APIs are exposed via Swagger or OpenApi). If that's not an option, writing a REST client from scratch is something I try to avoid as much as I can..

Flink provides official http api to submit jar jobs and query job status, and they might be able to help.

I use an extended version of the RestClusterClient that you can reuse if you want to. It is available at [1] and it add some missing methods to the default Flink version (I also had to copy that class and modify the visibility of some field in order to enable the extension). Officially the Flink RestClusterClient is meant to be used for internal use only but it actually work very well.

Could you share more about why you want to directly use the client?

I came across RestClusterClient, but I am not sure if its official. I can create my own client, but just wanted to check if there is anything official available already that I can leverage.
