> Unregister application from YARN resource manager outside the shutdown hook
> ---------------------------------------------------------------------------
>
> Key: SPARK-31625
> URL: https://issues.apache.org/jira/browse/SPARK-31625
> Project: Spark
> Issue Type: Improvement
> Components: YARN
> Affects Versions: 3.1.0
> Reporter: Terry Kim
> Assignee: Apache Spark
> Priority: Major
>
> Currently, an application is unregistered from YARN resource manager as a
> shutdown hook. In the scenario where the shutdown hook does not run (e.g.,
> timeouts, etc.), the application is not unregistered, resulting in YARN
> resubmitting the application even if it succeeded.
> For example, you could see the following on the driver log:
> {code:java}
> 20/04/30 06:20:29 INFO SparkContext: Successfully stopped SparkContext
> 20/04/30 06:20:29 INFO ApplicationMaster: Final app status: SUCCEEDED,
> exitCode: 0
> 20/04/30 06:20:59 WARN ShutdownHookManager: ShutdownHook '$anon$2' timeout,
> java.util.concurrent.TimeoutException
> java.util.concurrent.TimeoutException
> at java.util.concurrent.FutureTask.get(FutureTask.java:205)
> at
> org.apache.hadoop.util.ShutdownHookManager.executeShutdown(ShutdownHookManager.java:124)
> at
> org.apache.hadoop.util.ShutdownHookManager$1.run(ShutdownHookManager.java:95)
> {code}
> On the YARN RM side:
> {code:java}
> 2020-04-30 06:21:25,083 INFO
> org.apache.hadoop.yarn.server.resourcemanager.rmcontainer.RMContainerImpl:
> container_1588227360159_0001_01_000001 Container Transitioned from RUNNING to
> COMPLETED
> 2020-04-30 06:21:25,085 INFO
> org.apache.hadoop.yarn.server.resourcemanager.rmapp.attempt.RMAppAttemptImpl:
> Updating application attempt appattempt_1588227360159_0001_000001 with final
> state: FAILED, and exit status: 0
> 2020-04-30 06:21:25,085 INFO
> org.apache.hadoop.yarn.server.resourcemanager.rmapp.attempt.RMAppAttemptImpl:
> appattempt_1588227360159_0001_000001 State change from RUNNING to
> FINAL_SAVING on event = CONTAINER_FINISHED
> {code}
> You see that the final state of the application becomes FAILED since the
> container is finished before the application is unregistered.
