Sean Owen updated SPARK-9886:
-----------------------------
Fix Version/s: 2.0.0
> Validate usages of Runtime.getRuntime.addShutdownHook
> -----------------------------------------------------
>
> Key: SPARK-9886
> URL: https://issues.apache.org/jira/browse/SPARK-9886
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Reporter: Michel Lemay
> Assignee: Naveen Kumar Minchu
> Priority: Minor
> Fix For: 1.6.0, 2.0.0
>
>
> While refactoring calls to Utils.addShutdownHook to spark ShutdownHookManager
> in PR #8109, I've seen instances of calls to
> Runtime.getRuntime.addShutdownHook:
> org\apache\spark\deploy\ExternalShuffleService.scala:126
> org\apache\spark\deploy\mesos\MesosClusterDispatcher.scala:113
> org\apache\spark\storage\ExternalBlockStore.scala:181
> Comment from @vanzin:
> "From a quick look, it seems that at least the one in ExternalBlockStore
> should be changed; the other two seem to be separate processes (i.e. they are
> not part of a Spark application) so that's questionable. But I'd say leave it
> for a different change (maybe file a separate bug so it doesn't fall through
> the cracks)."
