> ---------------------------------------------------------------------

> Key: SPARK-22876
> URL: https://issues.apache.org/jira/browse/SPARK-22876
> Project: Spark
> Issue Type: Bug
> Components: YARN
> Affects Versions: 2.2.0
> Environment: hadoop version 2.7.3
> Reporter: Jinhan Zhong
> Priority: Minor
> Labels: bulk-closed
>
> I assume we can use spark.yarn.maxAppAttempts together with spark.yarn.am.attemptFailuresValidityInterval to make a long running application avoid stopping after acceptable number of failures.
> But after testing, I found that the application always stops after failing n times ( n is minimum value of spark.yarn.maxAppAttempts and yarn.resourcemanager.am.max-attempts from client yarn-site.xml)
> for example, following setup will allow the application master to fail 20 times.
> * spark.yarn.am.attemptFailuresValidityInterval=1s
> * spark.yarn.maxAppAttempts=20
> * yarn client: yarn.resourcemanager.am.max-attempts=20
> * yarn resource manager: yarn.resourcemanager.am.max-attempts=3
> And after checking the source code, I found in source file ApplicationMaster.scala https://github.com/apache/spark/blob/master/resource-managers/yarn/src/main/scala/org/apache/spark/deploy/yarn/ApplicationMaster.scala#L293
> there's a ShutdownHook that checks the attempt id against the maxAppAttempts, if attempt id >= maxAppAttempts, it will try to unregister the application and the application will finish.
> is this a expected design or a bug?
