Haibo Chen commented on YARN-7933:
----------------------------------
While thinking of the appId issue, there's one question that occurred to me.
Authentication is supported via Kerberos and Delegation Token. Where do we
check the delegation token on inside PerNodeTimelineCollectorService? I am not
able to find that information. Ideally, we need to check the token inside
individual collectors, so that one TimelineClient can not pretend to be a
client of another TimelineCollector than the one it is supposed to talk to, if
the two collectors happen to be on the same node.
