Summary: [Federation] Enhance Exception Handling in
FederationClientInterceptor#forceKillApplication
Key: YARN-11787
URL: https://issues.apache.org/jira/browse/YARN-11787
Project: Hadoop YARN
Issue Type: Improvement
Components: federation
Affects Versions: 3.5.0, 3.4.2
Reporter: Shilun Fan
Assignee: Shilun Fan
Currently, when handling {{{}forceKillApplication{}}}, we follow this logic:
first, we kill the Application in the {{{}HomeSubCluster{}}}, and then kill the
Applications in the other subclusters. This approach can lead to an issue
where, if a subcluster does not have the Application, the subcluster's RM
throws an "application not exists in RM" exception. In this case, we can safely
ignore the exception as it does not impact our normal processing flow.
