Fred Krone updated GEODE-2862:
------------------------------
Labels: storage_3 (was: )
> shutdown hook does not wait for disk store async tasks to complete
> ------------------------------------------------------------------
>
> Key: GEODE-2862
> URL: https://issues.apache.org/jira/browse/GEODE-2862
> Project: Geode
> Issue Type: Bug
> Components: persistence
> Affects Versions: 1.0.0-incubating
> Reporter: Darrel Schneider
> Labels: storage_3
>
> If you do a normal cache close and are using persistence then each disk store
> close will wait for all of its async background tasks to complete.
> But if instead the JVM shutdown hook is used (see
> java.lang.Runtime.addShutdownHook(Thread) for a description of what causes
> the shutdown hook to be called) then it will not wait for the async
> persistent tasks to complete.
> Both of these types of shutdown are considered an orderly shutdown (as
> opposed to a unorderly shutdown caused by things like a kill -9) and geode
> should only have one type of orderly shutdown. By not waiting for the async
> persistent tasks to complete some files may never be fully written.
> Here is the code that causes the shutdown hook to not wait in DiskStoreImpl:
> {code}
> // don't block the shutdown hook
> if (Thread.currentThread() != InternalDistributedSystem.shutdownHook) {
> waitForBackgroundTasks();
> }
> {code}
