     [ https://issues.apache.org/jira/browse/YARN-3666?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Botong Huang updated YARN-3666:
-------------------------------
    Description: 
In order, to support transparent "spanning" of jobs across sub-clusters, all AM-RM communications are proxied (via YARN-2884).

This JIRA tracks federation-specific mechanisms that decide how to "split/broadcast" requests to the RMs and "merge" answers to 
the AM.

This the part one jira, which sets up the basic structure, without secondary subclusters. All requests are forwarded to home subcluster.
