Botong Huang created YARN-6704:
----------------------------------
Summary: Add Federation Interceptor restart when work preserving
NM is enabled
Key: YARN-6704
URL: https://issues.apache.org/jira/browse/YARN-6704
Project: Hadoop YARN
Issue Type: Task
Reporter: Botong Huang
Assignee: Botong Huang
YARN-1336 added the ability to restart NM without loosing any running
containers. {{AMRMProxy}} restart is added in YARN-6127. In a Federated YARN
environment, there's additional state in the {{FederationInterceptor}} to allow
for spanning across multiple sub-clusters, so we need to enhance
{{FederationInterceptor}} to support work-preserving restart.
