Subject [jira] [Created] (HADOOP-11207) DelegationTokenAuthenticationHandler needs to support DT operations for proxy user

------------------------------------

             Summary: DelegationTokenAuthenticationHandler needs to support DT operations
for proxy user
                 Key: HADOOP-11207
                 URL: https://issues.apache.org/jira/browse/HADOOP-11207
             Project: Hadoop Common
          Issue Type: Bug
          Components: security
            Reporter: Zhijie Shen
            Assignee: Zhijie Shen


Currently, DelegationTokenAuthenticationHandler only support DT operations for the request
user after it passes the authentication. However, it should also support the request user
to do DT operations on behalf of the proxy user.

Timeline server is using the authentication filter for DT operations instead of traditional
RPC-based ones. It needs this feature to enable the proxy user to use the timeline service
(YARN-2676).
