Aaron T. Myers commented on HDFS-2617:
--------------------------------------
bq. If we have the config knob, it has to be something way more obvious that
you are basically turning off security.
What makes you say we're "basically turning off security"? The config knob
as-implemented is switching between using KSSL or SPNEGO for HTTP auth, not
disabling HTTP auth entirely.
> Replaced Kerberized SSL for image transfer and fsck with SPNEGO-based solution

> The current approach to secure and authenticate nn web services is based on
> Kerberized SSL and was developed when a SPNEGO solution wasn't available. Now
> that we have one, we can get rid of the non-standard KSSL and use SPNEGO
> throughout. This will simplify setup and configuration. Also, Kerberized
> SSL is a non-standard approach with its own quirks and dark corners
> (HDFS-2386).
