Summary: Proxying all AM-RM communications
Key: YARN-2884
URL: https://issues.apache.org/jira/browse/YARN-2884
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Carlo Curino
We introduce the notion of an RMProxy, running on each node (or once per rack).
Upon start the AM is forced (via tokens and configuration) to direct all its
requests to a new services running on the NM that provide a proxy to the
central RM.
This give us a place to:
1) perform distributed scheduling decisions
2) throttling mis-behaving AMs
3) mask the access to a federation of RMs
