Hey All, We are using the HZ Clustering extension and it's gone quite well. We did run into a problem around deleting styles and layers. It seems to allow the delete well, but doesn't sync the delete to the others in the cluster. So, then a catalog refresh is required. Was wondering if anyone else has seen this and if there is a configuration problem that I need to resolve to allow for this. We are in AWS and using EFS a shared data directory. Only have 3 in the cluster currently and all look to be healthy and able to communicate with each other.
Thanks, Jason We do run into this error as well: 2019-07-09 18:46:42,472 WARN [cluster.hazelcast] - 10.2.2.245:5701 - Event dispatch failed: REMOVE (/10.2.2.24:5701) [uuid:4efd2fe1-81f0-485d-a52e-9acb42d35d17, object id:StyleInfo.600ff7c7-c164-4cb3-84c3-0c54cef71216, name:Rich Test App] java.lang.reflect.InvocationTargetException at sun.reflect.GeneratedMethodAccessor400.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.geoserver.cluster.hazelcast.EventHzSynchronizer.processCatalogEvent(EventHzSynchronizer.java:262) at org.geoserver.cluster.hazelcast.EventHzSynchronizer.processEvent(EventHzSynchronizer.java:172) at org.geoserver.cluster.hazelcast.HzSynchronizer$EventWorker.call(HzSynchronizer.java:136) at org.geoserver.cluster.hazelcast.HzSynchronizer$EventWorker.call(HzSynchronizer.java:121) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$201(ScheduledThreadPoolExecutor.java:180) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:293) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Caused by: java.lang.NullPointerException at com.sun.proxy.$Proxy30.hashCode(Unknown Source) at java.util.HashMap.hash(HashMap.java:339) at java.util.HashMap.remove(HashMap.java:799) at org.geoserver.catalog.ResourcePool.clear(ResourcePool.java:2028) at org.geoserver.catalog.ResourcePool$CacheClearingListener.visit(ResourcePool.java:2463) at org.geoserver.cluster.hazelcast.RemovedObjectProxy.proxyVisitory(RemovedObjectProxy.java:140) at org.geoserver.cluster.hazelcast.RemovedObjectProxy.invoke(RemovedObjectProxy.java:103) at com.sun.proxy.$Proxy30.accept(Unknown Source) at org.geoserver.catalog.ResourcePool$CacheClearingListener.handleRemoveEvent(ResourcePool.java:2432) ... 13 more
