[jira] [Resolved] (CURATOR-39) ServiceProvider thread is not closed
during ServiceDiscovery close
[ https://issues.apache.org/jira/browse/CURATOR-39?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ioannis Canellos resolved CURATOR-39.
-------------------------------------
Resolution: Duplicate
Fix Version/s: (was: TBD)
2.3.0
Agree,
I think that the root cause falls back to the PatchChildrenCache issue with the ClosingExecutorService aka CURATOR-27.
Since, CURATOR-27 is now resolved, I think that we need to resolve this one too as duplicate.

> I'm using 2.0.1-incubating, using the following to build a ServiceProvider:
> serviceProvider = serviceDiscovery.serviceProviderBuilder()
> .serviceName(name)
> .providerStrategy(new RoundRobinStrategy<DiscoverableService>())
> .build();
> serviceProvider.start();
> I have a name => ServiceProvider map that stores all my service providers. During shutdown, I call:
> for (ServiceProvider serviceProvider : serviceProviderMap.values()) {
> serviceProvider.close();
> }
> serviceDiscovery.close();
> Which is redundant, it seems, because serviceDiscovery itself appears to shutdown the providers. However, I still end up with a dangling "ServiceProvider-0" thread that keeps Tomcat open.
> If I start the container up, without making a service call (so I don't allocate any ServiceProviders), Tomcat shuts down cleanly. As soon as a ServiceProvider is allocated (by making a service call) Tomcat hangs during shutdown, and informs me of the remaining thread. I will try to provide more information as it becomes available to me.
