How to use webhdfs in integration tests

I have an application that uses webhdfs that I would like to test.
For unit tests it's simple, since I can just mock the webhdfs client in my application, but I would like to create integration tests as well.

I know it's possible to run a full hadoop cluster inside a docker/VM and use it in the integration tests, but that would consume a lot of resources, when all I need is a simple rest api service.

Is there an existing solution for webhdfs server to be used in integration tests?
I'm hoping to avoid writing one for myself from scratch.
