Subject [jira] [Created] (YARN-6805) NPE in LinuxContainerExecutor due to null PrivilegedOperationException exit code
Date Tue, 11 Jul 2017 22:37:00 GMT
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.
