Hazelcast會警告「接到JoinRequest與反覆不同的包版本」

Question

從Hazlecast 3.0.x的升級到3.5.2，當兩個節點連接使用多播我看到這個在日誌中反覆..

節點1：

WARNING: [x.x.x.x]:5701 [hazelCluster] [3.5.2] Received a JoinRequest with a different packet version! This -> 4, Incoming -> 1, Sender -> /x.x.x.x 
Oct 12, 2015 11:57:15 AM com.hazelcast.cluster.impl.MulticastService 

節點2：

WARNING: [x.x.x.x]:5701 [hazelCluster] [3.5.2] Received a JoinRequest with a different packet version! This -> 4, Incoming -> 1, Sender -> /x.x.x.x 
Oct 12, 2015 11:53:52 AM com.hazelcast.cluster.impl.MulticastService 

Hazelcast網絡配置：

<network> 
    <join> 
     <multicast enabled="true"> 
      <multicast-group>224.2.2.4</multicast-group> 
      <multicast-port>34466</multicast-port> 
      <multicast-time-to-live>64</multicast-time-to-live> 
      <multicast-timeout-seconds>2</multicast-timeout-seconds> 
     </multicast> 
    </join> 
</network> 

Answer 1

好像有一箇舊版本的Hazelcast仍然在同一個網絡上運行，在更新多播IP/PORT之後問題就解決了。
