> they don't report the URL, which is important to understand the failure...I'm 
> investigating a shuffle failure, looking at INFO level logs, and in case of 
> failure, the url itself is not printed, but I can see in 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 base url at least, 
> I could make sure it was trying to connect in a secure way (--> protocol: 
> https)
> logging isSecureShuffle could also be useful, but url contains every needed 
> info we need in case of a failure
