this is what I'm seeing locally in pre-commit, I don't know what that means

That's the whole error: it expects that providers.yaml links to the webhdfs.rst and hdfs.rst rather than to index.rst

Hi @potiuk, can you pls review, I was able to deal with the static checks but now another test has failed tests / Test docker-compose quick start (pull_request), is this something I'm supposed to resolve? If yes, how do I do that coz I didn't use the files mentioned in the error

Don't worry about that one - it's a flaky test that we are dealing with separately.
