Subject [jira] [Commented] (HADOOP-9054) Add AuthenticationHandler that uses Kerberos but allows for an alternate form of authentication for browsers
Date Mon, 19 Nov 2012 16:53:58 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9054?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13500368#comment-13500368
] 

Robert Kanter commented on HADOOP-9054:
---------------------------------------

This is to make it easier for others to implement their own AuthenticationHandler that uses
Kerberos in some cases and their own authentication mechanism (which they have to implement
themselves; I'll be making an abstract class) in other cases (i.e. browser access).  So, I
don't think I'd call it chain-able, but maybe "mixed".

> It would be useful for some Oozie users if, when using Kerberos, that browser access
to the oozie web UI could be authenticated in a different way (w/o Kerberos).  This may be
useful for other projects using Hadoop-Auth, so this feature is to add a new AuthenticationHandler
that uses Kerberos by default, unless a browser (user-agents are configurable) is used, in
which case some other form of authentication can be used.
