Jason Lowe created YARN-4355:
--------------------------------
Summary: NPE while processing localizer heartbeat
Key: YARN-4355
URL: https://issues.apache.org/jira/browse/YARN-4355
Project: Hadoop YARN
Issue Type: Bug
Components: nodemanager
Affects Versions: 2.7.2
Reporter: Jason Lowe
While analyzing YARN-4354 I noticed a nodemanager was getting NPEs while
processing a private localizer heartbeat. I think there's a race where we can
cleanup resources for an application and therefore remove the app local
resource tracker just as we are trying to handle the localizer heartbeat.
