Eli Collins commented on HDFS-2617:
-----------------------------------
KSSL works on RHEL6, we've tested secure RHEL6 clusters w/o SPNEGO (you have
to install the JCE policy file or not use AES-256). Also, WebHDFS isn't yet a
reasonable Hftp replacement, eg you can't distcp files larger than 24kb (!),
see HDFS-3577.
Given that removing KSSL support is an incompatible change, this is our stable
branch, and that we can add SPNEGO support w/o removing KSSL support, I'm -1 on
a patch that removes KSSL entirely.

> 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).
