Kan Zhang commented on HADOOP-8779: ----------------------------------- On the server side, you can support both SIMPLE and DIEGST-MD5 (token) simultaneously. It's up to the client to choose which method to use. But the client side code needs to make a decision. Without an option to specify the desired behavior, the client code can only default to one behavior.
