Subject [jira] [Updated] (HADOOP-9392) Token based authentication and Single Sign On
Date Tue, 30 Jul 2013 13:25:51 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-9392?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kai Zheng updated HADOOP-9392:
------------------------------

    Attachment: TokenAuth-breakdown.pdf

This is the main breakdown doc. The whole TokenAuth work is divided into 3 parts: TokenAuth
Framework, TokenAuth implementation – HAS, and TokenAuth Integration. We define each of
them in the doc and opened JIRAs for them accordingly. We’re working on the further breakdown
in appropriate level and will update this initial doc soon when it’s complete.

> 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
