Kan Zhang commented on HADOOP-8779:
-----------------------------------
Just to clarify, IMO, a cluster may be configured to use SIMPLE + SIMPLE or
SIMPLE + TOKEN, but not both at the same time. I don't see a use case for both
at the same time. On the other hand, I do see the value of SIMPLE + SIMPLE
without the overhead of tokens (i.e., without simultaneously enabling SIMPLE +
TOKEN).
> Use tokens regardless of authentication type
