Subject [jira] [Commented] (YARN-986) YARN should use cluster-id as token service address
Date Tue, 11 Feb 2014 05:27:21 GMT

Vinod Kumar Vavilapalli commented on YARN-986:
----------------------------------------------

bq. Use the cluster-id for both HA and non-HA cases, but fallback to use RM address if need
be both on the server and client sides.
+1 for this idea.

> 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.
