Larry McCay commented on HADOOP-9392: ------------------------------------- Hey Daryn - I share many of the same questions. I wasn't sure whether some of them were a flawed interpretation on my part or whether that was truly what was being proposed. It may still be the former but at least I'm not alone. We do have a meetup being planned for the Summit where we can hash out these sorts issues. It seems to me that we will have to start with the threats and usecases that need to be accounted for rather than starting with a lot of implementation details. We will try and begin these discussions before the summit - as our time will be limited there. We'll try and make enough progress beforehand that we can set a manageable agenda for the meetup. We will post the meetup/design session details here and on the mailing lists once they are finalized. > Token based authentication and Single Sign On > --------------------------------------------- > > Key: HADOOP-9392 > URL: https://issues.apache.org/jira/browse/HADOOP-9392 > Project: Hadoop Common > Issue Type: New Feature > Components: security > Reporter: Kai Zheng > Assignee: Kai Zheng > Fix For: 3.0.0 > > Attachments: token-based-authn-plus-sso.pdf > > > 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.
