Question

我正在尝试为hazelcast 3.1使用分布式执行程序服务，并发现我无法使用submitToMember（任务，成员）。在我的例子中，10.69.108.60是我的本地机器，170.194.100.111是我的远程机器。当成员是我的本地计算机时，我能够在将来获得返回值，但如果成员是远程计算机，则会给我 TargetNotAMemberException 。以下是代码

public class DistExecutionTest {

    public static void main(String args[]){
        DistributedExecutor dex = new DistributedExecutor();

        try {
            Member member = new MemberImpl(new Address("170.194.100.111",5701), false );

            String msg;
                msg = dex.echoOnTheMember("Hey youuuu!", member);

            System.out.println(msg);
        } catch (UnknownHostException e1) {
            e1.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        } catch (ExecutionException e) {
            e.printStackTrace();
        }catch (Exception e) {
            e.printStackTrace();
        }


    }
}

和

public class DistributedExecutor {
        Config config;
        NetworkConfig network;
        JoinConfig join;

    DistributedExecutor(){
        config = new Config();
        network = config.getNetworkConfig();
//      network.setPort(5701);
        join = network.getJoin();
        join.getMulticastConfig().setEnabled(false);

        join.getTcpIpConfig().addMember("170.194.100.111").addMember("10.69.108.60").setEnabled(true);
        network.getInterfaces().setEnabled(true).addInterface("170.194.100.*").addInterface("10.69.108.*");
    }

    public String echoOnTheMember(String input, Member member) throws Exception {
        Callable<String> task = new DistObject(input);
        HazelcastInstance hz = Hazelcast.newHazelcastInstance(config);
        IExecutorService executorService = hz.getExecutorService("default");
        Future<String> future = executorService.submitToMember(task, member);
        String distObjectResult = future.get();
        return distObjectResult;
    }
}

和

public class Echo implements Callable<String>, Serializable, HazelcastInstanceAware {

    private static final long serialVersionUID = -3164053990811643392L;

    String message = null;
    transient HazelcastInstance localInstance;
    public Echo(String msg){
        message = msg;
    }

    @Override
    public String call() throws Exception {
        return localInstance.toString() + message;
    }

    @Override
    public void setHazelcastInstance(HazelcastInstance hazelcastInstance) {
        this.localInstance = hazelcastInstance;
    }

}

以下是本地计算机上的日志记录

Answer 1

您是否可以使用hz.getCluster（）。getMembers（）方法获取成员实例，并选择要发送到的成员实例，而不是直接创建成员实例？我想看看它是否是由你创建该成员的方式引起的。

Answer 2

我无法在评论中设置文字格式，所以我会另外给出答案。

因此，您遇到的问题是您的成员不会形成群集的原因。

您应该看到如下记录：

Members [2] {
    Member [192.168.1.104]:5701 this
    Member [192.168.1.104]:5702
}

这就是为什么我需要更多日志记录只是你的堆栈跟踪，但目前不提供任何更多的值。我需要看看Hazelcast关于加入其他集群的内容。

我需要看到这样的事情：

Answer 3

我也遇到了同样的错误。这是由echoonthemember函数

中的这一行引起的

HazelcastInstance hz = Hazelcast.newHazelcastInstance(config);

它创建默认或cfg config的新hazelcast实例。在这个实际上不存在的淡褐色的实例中搜索该成员。因此，错误消息显示为 TargetNotAMemberException。

要使其正常工作，只需在echoonthemember函数中传递创建的实例即可。例如，将它作为类DistributedExecutor中的成员变量并通过构造函数进行设置。然后，如果您的实际实例是'abcdef'，那么用作

IExecutorService executorService = abcdef.getExecutorService("default");

不要创建新的Hazelcast实例。

使用分布式执行程序服务执行任务时的TargetNotAMemberException - hazelcast
