Subject [jira] [Updated] (YARN-2049) Delegation token stuff for the timeline sever
Date Fri, 16 May 2014 16:37:15 GMT

     [ https://issues.apache.org/jira/browse/YARN-2049?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Zhijie Shen updated YARN-2049:
------------------------------

    Attachment: YARN-2049.2.patch

Fix a bug in the previous patch:

When creating the delegation token, we shouldn't use the current user to server as the owner
of the DT, because the current user is going to be the user of the timeline server.

On the other side, we also cannot use the remote user from AuthenticationFilter, because before
passing AuthenticationFilter, the user is still not logged in, and the remote user from HttpServletRequest
is going to be "dr.who" by default, given static user filter is applied before.

The right way is get the user name from authentication token, because at this point the kerberos
authentication is passed, and authentication token's user name is actually the client kerberos
principle, which is the right one we want to use.
