--------------------------------
Summary: NPE introduced by YARN-4958 (The file localization
process should allow...)
Key: YARN-5373
URL: https://issues.apache.org/jira/browse/YARN-5373
Project: Hadoop YARN
Issue Type: Bug
Components: nodemanager
Affects Versions: 2.9.0
Reporter: Haibo Chen
Assignee: Haibo Chen
YARN-4958 added support for wildcards in file localization. It introduces a NPE
at
{{code}}
for (File wildLink : directory.listFiles()) {
sb.symlink(new Path(wildLink.toString()),
new Path(wildLink.getName()));
}
{{code}}
When directory.listFiles returns null, NPE will cause the container fail to
launch.
