---------------------------------
Summary: Set delegation token service address at the server side
Key: YARN-3761
URL: https://issues.apache.org/jira/browse/YARN-3761
Project: Hadoop YARN
Issue Type: Improvement
Components: security
Reporter: Zhijie Shen
Nowadays, YARN components generate the delegation token without the service
address set, and leave it to the client to set. With our java client library,
it is usually fine. However, if users are using REST API, it's going to be a
problem: The delegation token is returned as a url string. It's so unfriendly
for the thin client to deserialize the url string, set the token service
address and serialize it again for further usage. If we move the task of
setting the service address to the server side, the client can get rid of this
trouble.
