Question

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）

任何人都知道发生了什么？

我的代码：

package com.senior.seguranca.csm.datamart.hazelcast;

import com.hazelcast.config.Config;
import com.hazelcast.core.Hazelcast;
import com.hazelcast.core.HazelcastInstance;
import com.hazelcast.core.IAtomicReference;
import com.hazelcast.core.IFunction;

public class HazelcastTest {

    public HazelcastTest() {
        Config config = new Config();
        config.setInstanceName("HAZELCAST_INSTANCE");
        HazelcastInstance hazelcastInstance = Hazelcast.getOrCreateHazelcastInstance(config);

        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();
    }
}

class MyFunction implements IFunction<String, String> {

    private String newItem;

    public MyFunction(String newItem) {
        this.newItem = newItem;
    }

    @Override
    public String apply(String item) {
        return newItem;
    }
}

如果您确定所有三个节点都具有相同的Hazelcast版本（请验证这一点，因为我认为第三个节点出于未知原因有旧版本），请在错误跟踪器中提交一个问题。< / p>
