Darrel Schneider created GEODE-2862:
---------------------------------------
Summary: 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
Reporter: Darrel Schneider
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}
