Hazelcast TargetNotMemberException：不是成員！目標

Question

我見過很多關於com.hazelcast.spi.exception.TargetNotMemberException: Not Member! target:

的帖子但是在這種情況下該怎麼辦？問：是否可以將捕獲異常，並做「hazelCastInstance.shutdown（）`」

而且它有可能在「錯誤的節點」看汽車無：「在隊列剩餘的遷移任務=> 1」

Hazelcast 3.7具有兩個節點的羣集。

完整的堆棧跟蹤：

TargetNotMemberException延伸RetryableHazelcastException進一步延伸HazelcastException，這樣你就可以趕上HazelcastException，然後關閉實例或您可以搭乘直接TargetNotMemberException和關機Hazelcast實例。你可以考慮下課。

TargetNotMemberException.java

你可以像這樣的代碼......

import java.io.PrintWriter; 
import java.io.StringWriter; 

import com.hazelcast.config.Config; 
import com.hazelcast.core.Hazelcast; 
import com.hazelcast.core.HazelcastException; 
import com.hazelcast.core.HazelcastInstance; 
import com.hazelcast.spi.exception.TargetNotMemberException; 

public class HazelcastExceptionTest { 
    public static void main(String[] args) { 
     Config config = new Config("instanceOne"); 
     HazelcastInstance instanceOne = Hazelcast.newHazelcastInstance(config); 

     try { 
      testTargetNotMemberException(); 
     } 
     catch (HazelcastException e) { 
      StringWriter trace = new StringWriter(); 
      PrintWriter eTrace = new PrintWriter(trace, true); 
      e.printStackTrace(eTrace); 
      System.out.println("exception " + trace.toString()); 
      instanceOne.shutdown(); 

     } 
    } 

    public static void testTargetNotMemberException() { 
     throw new TargetNotMemberException("TargetNotMemberException"); 
    } 
}
