Concerning the « Token » design, in HADOOP-9533, the Service Access Token targets a specific ressource (defined by the service URL) and have a low lifetime while in HADOOP-9392, the Identity Token can be used for any services? (belonging to at trusted tokenrealm) and doesnt have an expiration time. Both of them carry extended attributed for fined-grained access control decisions or for the service itself. I'm just curious to learn more about how the Unified Authorization Framework (Hadoop-9466) would used to common token to make decisions.

As you have noticed, someone has recently created a JIRA to allow new authentification mechanisms based on JaaS and SaSl in Hadoop. https://issues.apache.org/jira/browse/HADOOP-9479 His work could be very interesting for us since we're basically trying to implement a new authentification mechanism in order to keep the code backward compatible. Plus, his work could be coupled with https://github.com/biancini/Shibboleth-Authentication/tree/master/jaas_module which is a JaaS module for Shibboleth. But I guess, Shibboleth cannot be used as it is, since it doesnt provide token. Concerning the Common token, the idea, if I'm not wrong, is to insert the user attributes in it so Hadoop internal services won't need to call a pluggable function to get them. However, does that mean that the common token will also be transmitted to Hadoop internal service?? Because we already have a token to authentificate to Hadoop internal services ( Delegation Token, Job Token ...) and it means that we will have to deal with 2 tokens. Thanks for reading me.

For starting, I'd like to ask some questions about the subject, as I have no experience with Hadoop, some points are still unclear for me. 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 I've seen that the NameNode and JobTracker get informations about the user by using its username and a pluggable interface that maps the username to a set of groups that the user belongs. Is this method problematic at larger scale? What do we have to do in that case? Include the user informations in the token? 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)” Here also, what is the problem with the token based authentification kerberos? What does common token based authentification means? Is there a link with the interactions of Hadoop components (see link http://clustermania.blogspot.jp/2011/11/hadoop-how-it-manages-security.html) ?? These questions seem stupid but I really need to understand more about the subject before starting ^^. Oh BTW I'm doing my master research at the NII (National Institute of Informatic) in Tokyo, Its already late night so I might not be able to answer the same day. Best regards.
