> 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).
