----------------------------------
Summary: Public Localizer is exiting in NodeManager due to
NullPointerException
Key: YARN-9968
URL: https://issues.apache.org/jira/browse/YARN-9968
Project: Hadoop YARN
Issue Type: Bug
Components: nodemanager
Affects Versions: 3.1.0
Reporter: Tarun Parimi
Assignee: Tarun Parimi
The Public Localizer is encountering a NullPointerException and exiting.
{code:java}
ERROR localizer.ResourceLocalizationService
(ResourceLocalizationService.java:run(995)) - Error: Shutting down
java.lang.NullPointerException
at
org.apache.hadoop.yarn.server.nodemanager.containermanager.localizer.ResourceLocalizationService$PublicLocalizer.run(ResourceLocalizationService.java:981)
INFO localizer.ResourceLocalizationService
(ResourceLocalizationService.java:run(997)) - Public cache exiting
{code}
The NodeManager still keeps on running. Subsequent localization events for
containers keep encountering the below error, resulting in failed Localization
of all new containers.
{code:java}

When this happens, the NodeManager becomes usable only after a restart.
