Karthik Kambatla commented on YARN-614:
---------------------------------------
Will the hardware errors include IOException and SocketTimeoutException etc.?
> Retry attempts automatically for hardware failures or YARN issues and set
> default app retries to 1

> URL: https://issues.apache.org/jira/browse/YARN-614
> Project: Hadoop YARN
> Issue Type: Improvement
> Reporter: Bikas Saha
>
> Attempts can fail due to a large number of user errors and they should not be
> retried unnecessarily. The only reason YARN should retry an attempt is when
> the hardware fails or YARN has an error. NM failing, lost NM and NM disk
> errors are the hardware errors that come to mind.
