[infinispan-issues] [JBoss JIRA] (ISPN-4161) Remove cache command for caches not created on all nodes fails with CacheException and an NPE root cause

Remove cache command for caches not created on all nodes fails with CacheException and an NPE root cause -------------------------------------------------------------------------------------------------------- Key: ISPN-4161 URL: https://issues.jboss.org/browse/ISPN-4161 Project: Infinispan Issue Type: Bug Reporter: Vladimir Blagojevic Fix For: 8.1.0.Final While testing creation of intermediate caches for M/R tasks I noticed that remove command fails with CacheException and NPE if the cache has not been created on all nodes. The culprit is in RemoteCommandsFactory where the following line of code: registry.getNamedComponentRegistry(cacheName).getComponent(PersistenceManager.class) assumes that component with cacheName has been registered. org.infinispan.commons.CacheException: Error removing cache at org.infinispan.manager.DefaultCacheManager.removeCache(DefaultCacheManager.java:477) at org.infinispan.distexec.mapreduce.MapReduceTask.execute(MapReduceTask.java:421) at org.infinispan.distexec.mapreduce.DistributedIntermediateCacheFourNodesMapReduceTest.testIntermediateCacheNotCreatedOnAllNodes(DistributedIntermediateCacheFourNodesMapReduceTest.java:66) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.testng.internal.MethodInvocationHelper.invokeMethod(MethodInvocationHelper.java:80) at org.testng.internal.Invoker.invokeMethod(Invoker.java:714) at org.testng.internal.Invoker.invokeTestMethod(Invoker.java:901) at org.testng.internal.Invoker.invokeTestMethods(Invoker.java:1231) at org.testng.internal.TestMethodWorker.invokeTestMethods(TestMethodWorker.java:127) at org.testng.internal.TestMethodWorker.run(TestMethodWorker.java:111) at org.testng.TestRunner.privateRun(TestRunner.java:767) at org.testng.TestRunner.run(TestRunner.java:617) at org.testng.SuiteRunner.runTest(SuiteRunner.java:334) at org.testng.SuiteRunner.access$000(SuiteRunner.java:37) at org.testng.SuiteRunner$SuiteWorker.run(SuiteRunner.java:368) at org.testng.internal.thread.ThreadUtil$2.call(ThreadUtil.java:64) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:744) Caused by: org.infinispan.remoting.RemoteException: ISPN000217: Received exception from DistributedIntermediateCacheFourNodesMapReduceTest-NodeD-24545, see cause for remote stack trace at org.infinispan.remoting.transport.AbstractTransport.checkResponse(AbstractTransport.java:41) at org.infinispan.remoting.transport.AbstractTransport.parseResponseAndAddToResponseList(AbstractTransport.java:66) at org.infinispan.remoting.transport.jgroups.JGroupsTransport.invokeRemotely(JGroupsTransport.java:548) at org.infinispan.manager.DefaultCacheManager.removeCache(DefaultCacheManager.java:469) ... 22 more Caused by: org.infinispan.commons.CacheException: Problems invoking command. at org.infinispan.remoting.transport.jgroups.CommandAwareRpcDispatcher.handle(CommandAwareRpcDispatcher.java:219) at org.jgroups.blocks.RequestCorrelator.handleRequest(RequestCorrelator.java:457) at org.jgroups.blocks.RequestCorrelator.receiveMessage(RequestCorrelator.java:374) at org.jgroups.blocks.RequestCorrelator.receive(RequestCorrelator.java:247) at org.jgroups.blocks.MessageDispatcher$ProtocolAdapter.up(MessageDispatcher.java:668) at org.jgroups.JChannel.up(JChannel.java:711) at org.jgroups.stack.ProtocolStack.up(ProtocolStack.java:1030) at org.jgroups.protocols.RSVP.up(RSVP.java:187) at org.jgroups.protocols.FRAG2.up(FRAG2.java:165) at org.jgroups.protocols.FlowControl.up(FlowControl.java:370) at org.jgroups.protocols.FlowControl.up(FlowControl.java:381) at org.jgroups.protocols.tom.TOA.up(TOA.java:121) at org.jgroups.protocols.pbcast.GMS.up(GMS.java:1040) at org.jgroups.protocols.pbcast.STABLE.up(STABLE.java:234) at org.jgroups.protocols.UNICAST3.up(UNICAST3.java:404) at org.jgroups.protocols.pbcast.NAKACK2.handleMessage(NAKACK2.java:774) at org.jgroups.protocols.pbcast.NAKACK2.up(NAKACK2.java:570) at org.jgroups.protocols.FD_SOCK.up(FD_SOCK.java:296) at org.jgroups.protocols.Discovery.up(Discovery.java:379) at org.jgroups.protocols.TP.passMessageUp(TP.java:1502) at org.jgroups.protocols.TP$MyHandler.run(TP.java:1719) ... 3 more Caused by: java.lang.NullPointerException at org.infinispan.commands.RemoteCommandsFactory.fromStream(RemoteCommandsFactory.java:198) at org.infinispan.marshall.exts.ReplicableCommandExternalizer.fromStream(ReplicableCommandExternalizer.java:106) at org.infinispan.marshall.exts.CacheRpcCommandExternalizer.readObject(CacheRpcCommandExternalizer.java:151) at org.infinispan.marshall.exts.CacheRpcCommandExternalizer.readObject(CacheRpcCommandExternalizer.java:62) at org.infinispan.marshall.core.ExternalizerTable$ExternalizerAdapter.readObject(ExternalizerTable.java:404) at org.infinispan.marshall.core.ExternalizerTable.readObject(ExternalizerTable.java:212) at org.infinispan.marshall.core.JBossMarshaller$ExternalizerTableProxy.readObject(JBossMarshaller.java:152)
