Jason Lowe created YARN-400:
-------------------------------
Summary: RM can return null application resource usage report leading to NPE
in client
Key: YARN-400
URL: https://issues.apache.org/jira/browse/YARN-400
Project: Hadoop YARN
Issue Type: Bug
Components: resourcemanager
Affects Versions: 0.23.6, 2.0.3-alpha
Reporter: Jason Lowe
Assignee: Jason Lowe
Priority: Critical
RMAppImpl.createAndGetApplicationReport can return a report with a null resource usage report
if full access to the app is allowed but the application has no current attempt. This leads
to NPEs in client code that assumes an app report will always have at least an empty resource
usage report.
