我在同一台机器上运行三个 Hazelcast 节点,每个节点都尝试更改 AtomicReference。第一个和第二个节点运行没有问题,第三个节点抛出 HazelcastSerializationException。
Hazelcast 版本:Hazelcast 3.4.2 (20150326 - f6349a4)
有谁知道发生了什么?
线程“主”com.hazelcast.nio.serialization.HazelcastSerializationException 中的异常:无法写入数据实例!请改用#writeData(ObjectDataOutput out, Data data)。 在 com.hazelcast.nio.serialization.SerializationServiceImpl.writeObject(SerializationServiceImpl.java:272) 在 com.hazelcast.nio.serialization.ByteArrayObjectDataOutput.writeObject(ByteArrayObjectDataOutput.java:262) 在 com.hazelcast.concurrent.atomicreference.operations.AbstractAlterOperation.writeInternal(AbstractAlterOperation.java:61) 在 com.hazelcast.spi.Operation.writeData(Operation.java:281) 在 com.hazelcast.nio.serialization.DataSerializer.write(DataSerializer.java:140) 在 com.hazelcast.nio.serialization.DataSerializer.write(DataSerializer.java:39) 在 com.hazelcast.nio.serialization.StreamSerializerAdapter.toData(StreamSerializerAdapter.java:51) 在 com.hazelcast.nio.serialization.SerializationServiceImpl.toData(SerializationServiceImpl.java:222) 在 com.hazelcast.nio.serialization.SerializationServiceImpl.toData(SerializationServiceImpl.java:203) 在 com.hazelcast.spi.impl.NodeEngineImpl.toData(NodeEngineImpl.java:180) 在 com.hazelcast.spi.impl.BasicOperationService.send(BasicOperationService.java:348) 在 com.hazelcast.spi.impl.BasicInvocation.doInvokeRemote(BasicInvocation.java:288) 在 com.hazelcast.spi.impl.BasicInvocation.doInvoke(BasicInvocation.java:260) 在 com.hazelcast.spi.impl.BasicInvocation.invoke(BasicInvocation.java:229) 在 com.hazelcast.spi.impl.BasicOperationService.invokeOnPartition(BasicOperationService.java:272) 在 com.hazelcast.concurrent.atomicreference.AtomicReferenceProxy.asyncInvoke(AtomicReferenceProxy.java:56) 在 com.hazelcast.concurrent.atomicreference.AtomicReferenceProxy.asyncAlterAndGet(AtomicReferenceProxy.java:87) 在 com.hazelcast.concurrent.atomicreference.AtomicReferenceProxy.alterAndGet(AtomicReferenceProxy.java:78) 在 com.senior.seguranca.csm.datamart.hazelcast.HazelcastTest.(HazelcastTest.java:18) 在 com.senior.seguranca.csm.datamart.hazelcast.HazelcastTest.main(HazelcastTest.java:22)

IAtomicReference<String> atomicReference = hazelcastInstance.getAtomicReference("TEST");
String item = "A";
System.out.println("Item: " + atomicReference.alterAndGet(new MyFunction(item)));
}
public static void main(String[] args) {
new HazelcastTest();

this.newItem = newItem;
}
@Override
