Date Thu, 21 Feb 2019 17:40:00 GMT

     [ https://issues.apache.org/jira/browse/SPARK-26954?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Marcelo Vanzin resolved SPARK-26954.
------------------------------------
    Resolution: Not A Problem

See discussion in the PR for why this is not a problem (or something that Spark should try
to solve).

>                 Key: SPARK-26954
>                 URL: https://issues.apache.org/jira/browse/SPARK-26954
>             Project: Spark
>          Issue Type: Improvement
>          Components: YARN
>    Affects Versions: 2.3.3, 2.4.0
>            Reporter: deshanxiao
>            Priority: Critical
>
> Yarn attemps the failed App depending on YarnRMClient#unregister. However, some attemps
are useless like the example:
> {code:java}
> sc.parallelize(Seq(1,2,3)).map(_ => throw new RuntimeException("exception")).collect()
> {code}
> Also some attemps when "FileNorFoundException" is thrown in user code looks unreasonable.
> Some environment errors, such as node dead, attemps reasonablely. So, it will be better
that user exception will not attemp.
