Zhijie Shen created YARN-3725:
---------------------------------

             Summary: App submission via REST API is broken in secure mode due 
to Timeline DT service address is empty
                 Key: YARN-3725
                 URL: https://issues.apache.org/jira/browse/YARN-3725
             Project: Hadoop YARN
          Issue Type: Bug
          Components: resourcemanager, timelineserver
    Affects Versions: 2.7.0
            Reporter: Zhijie Shen
            Assignee: Zhijie Shen
            Priority: Blocker


YARN-2971 changes TimelineClient to use the service address from Timeline DT to 
renew the DT instead of configured address. This break the procedure of 
submitting an YARN app via REST API in the secure mode.

The problem is that service address is set by the client instead of the server 
in Java code. REST API response is an encode token Sting, such that it's so 
inconvenient to deserialize it and set the service address and serialize it 
again.
