Daryn Sharp commented on YARN-986:
----------------------------------
This sounds like NN HA tokens which IMHO are rather hacky. I've been intending
to take advantage of my RPCv9 auth changes for the server to tell the client
the token service (or perhaps another field) it needs to decouple tokens
entirely from IP/hostname. Thoughts on this approach?
> YARN should have a ClusterId/ServiceId

> This needs to be done to support non-ip based fail over of RM. Once the
> server sets the token service address to be this generic ClusterId/ServiceId,
> clients can translate it to appropriate final IP and then be able to select
> tokens via TokenSelectors.
> Some workarounds for other related issues were put in place at YARN-945.
