Problem with capacityFactor=0 and restart of all nodes with capacityFactor > 0 ------------------------------------------------------------------------------ Key: ISPN-4996 URL: https://issues.redhat.com/browse/ISPN-4996 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 7.0.2.Final Reporter: Enrico Olivelli Assignee: Dan Berindei Priority: Blocker I have a only one DIST_SYNC cache, most of the JVM in the cluster are configured with capacityFactor = 0 (like the distibutedlocalstorage=false property of Coherence) and some node are configured with capacityFactor>0 (for instance 1000). We are talking about 100 nodes with capacityFactor=0 and 4 nodes of the other kind, al the cluster is indide one single "site/rack". Partition Handling is off, numOwners is 1. When all the nodes with capacityFactor > 0 are down the cluster comes to a degraded state the ploblem is that even if nodes with capacityFactor>0 are up again the cluster does not recover, a full restart is needed If I enable partition-handling AvailablyExceptions start to be throw and I think is the expected behaviour (see the "Infinispan User Guide"). I think this is the problem and it is a bug: {noformat} 14/11/17 09:27:25 WARN topology.CacheTopologyControlCommand: ISPN000071: Caught exception when handling command CacheTopologyControlCommand{cache=shared, type=JOIN, sender=testserver1@xxxxxxx-22311, site-id=xxx, rack-id=xxx, machine-id=24 bytes, joinInfo=CacheJoinInfo{consistentHashFactory=org.infinispan.distribution.ch.impl.TopologyAwareConsistentHashFactory@78b791ef, hashFunction=MurmurHash3, numSegments=60, numOwners=1, timeout=120000, totalOrder=false, distributed=true}, topologyId=0, rebalanceId=0, currentCH=null, pendingCH=null, availabilityMode=null, throwable=null, viewId=3} java.lang.IllegalArgumentException: A cache topology's pending consistent hash must contain all the current consistent hash's members at org.infinispan.topology.CacheTopology.<init>(CacheTopology.java:48) at org.infinispan.topology.CacheTopology.<init>(CacheTopology.java:43) at org.infinispan.topology.ClusterCacheStatus.startQueuedRebalance(ClusterCacheStatus.java:631) at org.infinispan.topology.ClusterCacheStatus.queueRebalance(ClusterCacheStatus.java:85) at org.infinispan.partionhandling.impl.PreferAvailabilityStrategy.onJoin(PreferAvailabilityStrategy.java:22) at org.infinispan.topology.ClusterCacheStatus.doJoin(ClusterCacheStatus.java:540) at org.infinispan.topology.ClusterTopologyManagerImpl.handleJoin(ClusterTopologyManagerImpl.java:123) at org.infinispan.topology.CacheTopologyControlCommand.doPerform(CacheTopologyControlCommand.java:158) at org.infinispan.topology.CacheTopologyControlCommand.perform(CacheTopologyControlCommand.java:140) at org.infinispan.remoting.transport.jgroups.CommandAwareRpcDispatcher$4.run(CommandAwareRpcDispatcher.java:278) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) {noformat} After that error every "put" results in: {noformat} 14/11/17 09:27:27 ERROR interceptors.InvocationContextInterceptor: ISPN000136: Execution error org.infinispan.util.concurrent.TimeoutException: Timed out waiting for topology 1 at org.infinispan.statetransfer.StateTransferLockImpl.waitForTransactionData(StateTransferLockImpl.java:93) at org.infinispan.interceptors.base.BaseStateTransferInterceptor.waitForTransactionData(BaseStateTransferInterceptor.java:96) at org.infinispan.statetransfer.StateTransferInterceptor.handleNonTxWriteCommand(StateTransferInterceptor.java:188) at org.infinispan.statetransfer.StateTransferInterceptor.visitPutKeyValueCommand(StateTransferInterceptor.java:95) at org.infinispan.commands.write.PutKeyValueCommand.acceptVisitor(PutKeyValueCommand.java:71) at org.infinispan.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:98) at org.infinispan.interceptors.CacheMgmtInterceptor.updateStoreStatistics(CacheMgmtInterceptor.java:148) at org.infinispan.interceptors.CacheMgmtInterceptor.visitPutKeyValueCommand(CacheMgmtInterceptor.java:134) at org.infinispan.commands.write.PutKeyValueCommand.acceptVisitor(PutKeyValueCommand.java:71) at org.infinispan.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:98) at org.infinispan.interceptors.InvocationContextInterceptor.handleAll(InvocationContextInterceptor.java:102) at org.infinispan.interceptors.InvocationContextInterceptor.handleDefault(InvocationContextInterceptor.java:71) at org.infinispan.commands.AbstractVisitor.visitPutKeyValueCommand(AbstractVisitor.java:35) at org.infinispan.commands.write.PutKeyValueCommand.acceptVisitor(PutKeyValueCommand.java:71) at org.infinispan.interceptors.InterceptorChain.invoke(InterceptorChain.java:333) at org.infinispan.cache.impl.CacheImpl.executeCommandAndCommitIfNeeded(CacheImpl.java:1576) at org.infinispan.cache.impl.CacheImpl.putInternal(CacheImpl.java:1054) at org.infinispan.cache.impl.CacheImpl.put(CacheImpl.java:1046) at org.infinispan.cache.impl.CacheImpl.put(CacheImpl.java:1646) at org.infinispan.cache.impl.CacheImpl.put(CacheImpl.java:245) {noformat} This is the actual configuration: {code:java} GlobalConfiguration globalConfig = new GlobalConfigurationBuilder() .globalJmxStatistics() .allowDuplicateDomains(true) .cacheManagerName(instanceName) .transport() .defaultTransport() .clusterName(clustername) .addProperty("configurationFile", configurationFile) (udp for my cluster, approx 100 machines) .machineId(instanceName) .siteId("site1") .rackId("rack1") .nodeName(serviceName + "@" + instanceName) .remoteCommandThreadPool().threadPoolFactory(CachedThreadPoolExecutorFactory.create()) .build();

{code} One workaround is to set capacityFactor = 1 instead of 0, but I do not want "simple-nodes" (with less RAM) to becaome key-owners For me this is a showstopper problem
