Larry McCay commented on KNOX-1032:
-----------------------------------
Hi [~ibuclaw] - Sorry, I don't have enough clarity on the current state of this
JIRA and I guess I failed to ask properly.
Let me try again.
Given that this JIRA didn't have any real movement for over 3 years now, I
assume that timeline server is indeed covered by Yarn UI as suggested by
[~smore]. This may not actually be true and there may have not been any
coverage of timeline server within that existing Yarn UI service definition.
However, if that is true and you are only seeing a particular link type as not
being proxied properly via the Yarn UI (and its service def) then we probably
just have a bug in the service def for that particular link.
What I'd like to know is whether that latter statement is true or whether you
are not able to get to any of the timeline server through the Yarn UI and
therefore the original assertion was actually untrue.
Hopefully that is more clear and apologies for any previous confusion.
[~smore] - would you happen to have any new insights into the current Yarn UI
vs timeline server service defs from over the past 3 years?
