Karthik Kambatla commented on YARN-986:
---------------------------------------

[~bikassaha], along with other changes, I added {{HAUtil#getLogicalName()}} in YARN-1232.
Do you think we can just use the same?

> 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.
