Shane Kumpf commented on YARN-6805:
-----------------------------------
Thanks for addressing this, [~jlowe].
LGTM less one very minor nit: Missing a space in the not null check below.
{code}
+ String output = e.getOutput();
+ if (output!= null && !e.getOutput().isEmpty()) {
+ builder.append("Shell output: " + output + "\n");
}
{code}
> NPE in LinuxContainerExecutor due to null PrivilegedOperationException exit

> 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
> Assignee: 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.
