Jakob Homan commented on HDFS-8155:
-----------------------------------
bq. I agree when an initial authentication like Kerberos/SPNEGO is passed, a DT
will need to be generated and passed to the server in all subsequent usages.
Why would it need to be? A backing store could accept a delegation token, or
the datanodes could continue to accept the SPENGO/Kerberos credentials or OAuth
tokens. DTs are one option, but I do not want to rule out
datanodes/datanode-like-servers accepting standard credentials.
