Oleg Zhurakousky commented on YARN-1841:
----------------------------------------
Au contraire ;) The issue is very valid as stated. Even if it were to change to
a simple documentation issue it is still an issue never the less.
The gist of it is my authentication is explicitly set to SIMPLE and is
overridden to TOKEN without any log message or exception telling me that it is
invalid (see the code above) or that its overridden.
Personally I suspect its an overall deign problem. If Token must be present
then the underlying API must be structured as such, but that is a different
discussion.
Cheers
