--------------------------------
Summary: LinuxContainerExecutor.deleteAsUser can throw NPE if
native executor returns an error
Key: YARN-3088
URL: https://issues.apache.org/jira/browse/YARN-3088
Project: Hadoop YARN
Issue Type: Bug
Components: nodemanager
Affects Versions: 2.1.1-beta
Reporter: Jason Lowe
If the native executor returns an error trying to delete a path as a particular
user when dir==null then the code can NPE trying to build a log message for the
error. It blindly deferences dir in the log message despite the code just
above explicitly handling the cases when dir could be null.
