Daryn Sharp commented on HDFS-4056:
-----------------------------------

SIMPLE is still supported as it currently is today.  The difference is that a SIMPLE auth connection may also use a token, whereas today an insecure cluster will kick a client back into SIMPLE auth if it attempts to negotiate DIGEST-MD5 with a token.  Clients are not strictly required to use a token.
