Robert Joseph Evans commented on MAPREDUCE-3706:
------------------------------------------------
The only time that this would happen is if the AM thinks that the request is
not coming from the proxy, and is then being redirected to go through the proxy
again. I will look to see exactly which conditions this happens in. It could
be that if the user is null, then this might happen.
