Subject [jira] Commented: (HADOOP-7119) add Kerberos HTTP SPNEGO authentication support to Hadoop JT/NN/DN/TT web-consoles
Date Mon, 07 Feb 2011 05:19:31 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7119?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12991264#comment-12991264
] 

eric baldeschwieler commented on HADOOP-7119:
---------------------------------------------

It would be great to get SPNEGO support checked into hadoop, rather than picking up an external
dependency for a small amount of just written code (assuming no preexisting code solves the
problem).  Especially given that this is security code and that it doesn't have a community
beyond hadoop, having it in the project seems like a good idea.

This isn't to say that others can't use it right away, but any modification to hadoop consoles
won't ship until hadoop does a release anyway, so there is no reason not to add the functionality
in "alfredo" into hadoop common with this patch, is there?

> Currently the JT/NN/DN/TT web-consoles don't support any form of authentication.
> Hadoop RPC API already supports Kerberos authentication.
> Kerberos enables single sign-on.
> Popular browsers (Firefox and Internet Explorer) have support for Kerberos HTTP SPNEGO.
> Adding support for Kerberos HTTP SPNEGO to Hadoop web consoles would provide a unified
authentication mechanism and single sign-on for Hadoop web UI and Hadoop RPC.
