Subject [jira] [Commented] (HDFS-5796) The file system browser in the namenode UI requires SPNEGO.
Date Fri, 17 Jan 2014 19:52:20 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5796?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13875192#comment-13875192

Haohui Mai commented on HDFS-5796:
----------------------------------

WebHDFS is designed to be a gateway for all third-party services where SPNEGO might not be
available. 
In my opinion WebHDFS should support the same  authentication mechanisms as the one the web
UI supports.

> After HDFS-5382, the browser makes webhdfs REST calls directly, requiring SPNEGO to work
between user's browser and namenode.  This won't work if the cluster's security infrastructure
is isolated from the regular network.  Moreover, SPNEGO is not supposed to be required for
user-facing web pages.
