      Due to the requirement that KSSL use weak encryption types for Kerberos tickets, HTTP authentication to the NameNode will now use SPNEGO by default. This will require users of previous branch-1 releases with security enabled to modify their configurations and create new Kerberos principals in order to use SPNEGO. The old behavior of using KSSL can optionally be enabled by setting the configuration option "hadoop.security.use-weak-http-crypto" to "true".

      Description

      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).
