Daryn Sharp commented on HADOOP-8779:
-------------------------------------
I believe you are misunderstanding the patch, or I have an unintentional bug.
To save people a trip to HDFS-4056, here's the relevant info:
bq. 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.
> Use tokens regardless of authentication type
