> they don't report the full URL, which is important to understand the
> failure...I'm investigating a shuffle failure, looking at an INFO level logs,
> and in case of failure, the url itself is not printed, but I can see int the
> ShuffleHandler logs that the request is not a valid ssl request, which makes
> me think that fetcher simply works with invalid settings...if I saw the full
> url, I could make sure it was trying to connect in a secure way (-->
> protocol: https)
> logging isSecureShuffle could also be useful, but full url contains every
> needed info we need in case of a failure
