Subject [jira] [Commented] (HADOOP-9392) Token based authentication and Single Sign On
Date Sat, 08 Jun 2013 18:27:22 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9392?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13678805#comment-13678805

Andrew Purtell commented on HADOOP-9392:
----------------------------------------

bq. Currently, a room has been allocated on the 26th from 1:45 to 3:30 PT. Specific location
will be available at the Summit and any changes in date or time will be announced publicly
to the best of our abilities. In order to create a manageable agenda for this session, I'd
like to schedule some prep meetings via meetup.com.

[~kevin.minder] Is there a link to that meetup group?

> This is an umbrella entry for one of project Rhino’s topic, for details of project
Rhino, please refer to https://github.com/intel-hadoop/project-rhino/. The major goal for
this entry as described in project Rhino was 
>  
> “Core, HDFS, ZooKeeper, and HBase currently support Kerberos authentication at the
RPC layer, via SASL. However this does not provide valuable attributes such as group membership,
classification level, organizational identity, or support for user defined attributes. Hadoop
components must interrogate external resources for discovering these attributes and at scale
this is problematic. There is also no consistent delegation model. HDFS has a simple delegation
capability, and only Oozie can take limited advantage of it. We will implement a common token
based authentication framework to decouple internal user and service authentication from external
mechanisms used to support it (like Kerberos)”
>  
> We’d like to start our work from Hadoop-Common and try to provide common facilities
by extending existing authentication framework which support:
> 1.	Pluggable token provider interface 
> 2.	Pluggable token verification protocol and interface
> 3.	Security mechanism to distribute secrets in cluster nodes
> 4.	Delegation model of user authentication
