Michel Lemay created SPARK-9886:
-----------------------------------
Summary: 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
Priority: Minor
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)."
