Karthik Kambatla commented on YARN-986:
---------------------------------------
IMO, the following approach should address the need: ({{rpc-address}} refers to
each of {{address}}, {{scheduler.address}}, {{admin.address}},
{{resource-tracker.address}}, {{webapp.address}})
# {{yarn.resourcemanager.clusterid}} gives the clusterid/logical name (e.g.
foo), and the actual RPC addresses for the cluster are to be specified as
{{yarn.resourcemanager.<rpc-address>.foo}}
# Helper class {{ConfigurationUtil}} adds variants of getClusterId(), get/set
(<rpc-address>, clusterid) methods.
# RM uses the above helper methods to set all the rpc-addresses during init for
the servers to use. If no cluster-id, the <rpc-addresses> are used as is, so
current configurations continue to work as expected.
# The individual RPC services remain unchanged.
# Clients can direct their queries to a particular cluster by setting either
the cluserid, or <rpc-address>.
# This trivially extends to HA clusters - the RPC addresses become
{{yarn.resourcemanager.<rpc-address>.clusterid.instanceid}}
Thoughts?
> 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.
