Subject [jira] [Created] (YARN-3088) LinuxContainerExecutor.deleteAsUser can throw NPE if native executor returns an error
Date Thu, 22 Jan 2015 20:41:34 GMT
Jason Lowe created YARN-3088:
--------------------------------

             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.
