Wangda Tan commented on YARN-7974:
----------------------------------
[~jhung],
Thanks for working on the feature, I can see it's values.
For implementation / API:
1) Have you considered only allowing AM to update the tracking URL? Which can
solve some problems like: a. Need to properly check ACL to make the change. b.
concurrent write tracking URL causes issue.
2) I think the updated tracking URL need to be persisted as well, otherwise RM
restart causes update information cleared.

> Normally an application's tracking url is set on AM registration. We have a
> use case for updating the tracking url after registration (e.g. the UI is
> hosted on one of the containers).
> Currently we added a {{updateTrackingUrl}} API to ApplicationClientProtocol.
> We'll post the patch soon, assuming there are no issues with this.
