Jason Lowe updated YARN-6805:
-----------------------------
Attachment: YARN-6805.001.patch
Attaching a patch that removes the Integer support for an exit code and just
always returns an int. All the code calling getExitCode for
PrivilegedOperationException and ContainerExecutionException doesn't expect a
null exit code, and ContainerExecutionException already has the precedent of
using -1 to indicate a lack of an exit code.
> 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
> Attachments: YARN-6805.001.patch
>
>
> 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.
