------------------------------------------
Summary: Add management hook to AuthenticationHandler to enable
delegation token operations support
Key: HADOOP-8458
URL: https://issues.apache.org/jira/browse/HADOOP-8458
Project: Hadoop Common
Issue Type: New Feature
Components: security
Affects Versions: 2.0.1-alpha
Reporter: Alejandro Abdelnur
Assignee: Alejandro Abdelnur
Fix For: 2.0.1-alpha
Currently hadoop-auth AuthenticationHandler only authenticates a request.
While it can easily be extended to authenticate delegation tokens, it cannot
handle the delegation token get/renew/cancel operations.
The motivation of this new feature is that the above delegation token
operations should be handled by a security component (hadoop-auth) instead of a
functional component (httpfs implementation). Ideally we should have a complete
separation of concerns between delegation token management and
FileSystem/MapReduce/YARN API, but we don't. This change is a step on that
directory for HTTP based services (like HttpFS).
