Subject [jira] [Updated] (HDFS-2617) Replaced Kerberized SSL for image transfer and fsck with SPNEGO-based solution
Date Thu, 03 May 2012 21:44:48 GMT

     [ https://issues.apache.org/jira/browse/HDFS-2617?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Owen O'Malley updated HDFS-2617:
--------------------------------

    Attachment: HDFS-2617-config.patch

I'd like to add default values for the new config knobs so that if the user already has webhdfs
configured, they don't need to do anything extra.

> 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).
