Alejandro Abdelnur commented on YARN-986:
-----------------------------------------
Hey [~daryn], you told be a bit about it during the HS, but I don't recall the
details. Would you elaborate how RPCv9 could be used to get rid of setting the
service in the tokens? (both in secure and un-secure modes).
> YARN should have a ClusterId/ServiceId

> Key: YARN-986

> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Vinod Kumar Vavilapalli
> Assignee: Karthik Kambatla
>
> 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.
