Subject [jira] [Commented] (HDFS-2617) Replaced Kerberized SSL for image transfer and fsck with SPNEGO-based solution
Date Thu, 19 Jul 2012 12:32:37 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2617?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13418251#comment-13418251
] 

Owen O'Malley commented on HDFS-2617:
-------------------------------------

Todd, KSSL is the unfortunate choice and needs to be phased out as quickly as possible.

Aaron, I have patches that apply on top that fix HSFTP to work correctly.

> 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).
