Summary: Make the NodeManager's health checker service pluggable
Key: YARN-4271
URL: https://issues.apache.org/jira/browse/YARN-4271
Project: Hadoop YARN
Issue Type: Sub-task
Components: nodemanager, resourcemanager
Reporter: Subru Krishnan
Assignee: Kishore Chaliparambil
Fix For: 2.8.0
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
