To implement and integrate pluggable authentication providers, enhance desirable single sign on for end users, and help enforce centralized access control on the platform, the community has widely discussed and concluded token based authentication could be the appropriate approach. TokenAuth (HADOOP-9392) was proposed and is under development to implement another Authentication Method in lieu with Simple and Kerberos. It is a big and long term effort to support TokenAuth across the entire ecosystem. We here propose a short term replacement based on Kerberos that can complement to TokenAuth. Our solution involves less codes changes with limited risk and the main development work has already been done in our POC. Users can use our solution as a short term solution to support token inside Hadoop.
This effort and resultant solution will be fully described in the design document to be attached. And the brief introduction will be commented.
