             Summary: Unified authorization framework
                 Key: HADOOP-9466
                 URL: https://issues.apache.org/jira/browse/HADOOP-9466
             Project: Hadoop Common
          Issue Type: Improvement

            Reporter: Kai Zheng

This is an umbrella entry for one of project Rhino’s goal, “common authorization framework
for the Hadoop ecosystem”. For details of project Rhino and the goal, please refer to https://github.com/intel-hadoop/project-rhino/.

We’d like to start this work from Hadoop-Common, based on token based authentication (HADOOP-9392),
provide an unified and common authorization framework as follows:
1. Abstract and extensible denote for authorization resources;
2. Unified authorization policy and configuration;
3. Unified and pluggable authorization enforcement engine;
4. Authorization trust transferring and management;
And based on this framework,
5. Role based access control;
6. Default implementation of service level authorization with backward compatibility;
7. Extended file ACL for HDFS

As design considerations, we keep the following in mind:
1. Authorization enforcement is done with input policies and common authentication token;
2. Authorization configuration and policy management is separated from authorization enforcement;
3. Allows to support advanced authorization model, such as ABAC and XACML standard;
4. Allows to support domain based authorization for multi-tenancy scenario;
5. Unified access control exception message for log.
