Jason Lowe created YARN-6805:
--------------------------------
Summary: NPE in LinuxContainerExecutor due to null
PrivilegedOperationException exit code
Key: YARN-6805
URL: https://issues.apache.org/jira/browse/YARN-6805
Project: Hadoop YARN
Issue Type: Bug
Components: nodemanager
Affects Versions: 2.8.1
Reporter: Jason Lowe
The LinuxContainerExecutor contains a number of code snippets like this:
{code}
} catch (PrivilegedOperationException e) {
int exitCode = e.getExitCode();
{code}
PrivilegedOperationException#getExitCode can return null if the operation was
interrupted, so when the JVM does auto-unboxing on that last line it can NPE if
there was no exit code.
