             Summary: DeletionService can silently ignore deletion task failures
                 Key: YARN-3090
                 URL: https://issues.apache.org/jira/browse/YARN-3090
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 2.1.1-beta
            Reporter: Jason Lowe

If a non-I/O exception occurs while the DeletionService is executing a deletion 
task then it will be silently ignored.  The exception bubbles up to the thread 
workers of the ScheduledThreadPoolExecutor which simply attaches the throwable 
to the Future that was returned when the task was scheduled.  However the 
thread pool is used as a fire-and-forget pool, so nothing ever looks at the 
Future and therefore the exception is never logged.
