Attachment: YARN-3090.002.patch
> 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
> Assignee: Varun Saxena
> Attachments: YARN-3090.001.patch, YARN-3090.002.patch
>
>
> 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.
