It is not possible to edit the "run_as_user_name" property after the job is created. However, you can submit the run without creating a job by using the Databricks API directly and passing the "run_as_user_name" parameter explicitly. If you are using the Databricks 2.0 API, the "run_as_user_name" parameter may not be supported, and you may need to upgrade to the Databricks 2.1 AP

You can authenticate using a Personal Access Token (PAT) or an SSH key. If you are using a PAT, you don't need to provide the SSH key and known_hosts files. The Git configuration should look like this:

git:
  auth:
    type: token
    token: my_git_credentials_token

You can provide the PAT value directly in the "token" field.
