尝试从我的本地计算机连接到点燃缓存时出现 IgniteSpiException

Question

我有一个使用 IgniteDb 作为缓存提供程序的应用程序。它使用发现 url 作为： 127.0.0.1:47500..47509。现在我想在 Eclipse 中使用 java 代码连接到这个缓存。我把代码写成：

 IgniteConfiguration cfg = new IgniteConfiguration().setBinaryConfiguration(
           new BinaryConfiguration().setNameMapper(new BinaryBasicNameMapper(true)));
TcpDiscoveryMulticastIpFinder discoveryMulticastIpFinder = new TcpDiscoveryMulticastIpFinder();
       Set<String> set = new HashSet<>();

       set.add("127.0.0.1:47500..47509");
       cfg.setPeerClassLoadingEnabled (true);
       TcpDiscoverySpi discoverySpi = new TcpDiscoverySpi();

       discoveryMulticastIpFinder.setAddresses(set);
       discoverySpi.setNetworkTimeout (5000);

    discoverySpi.setClientReconnectDisabled(true);

    cfg.setDiscoverySpi(discoverySpi);

       discoverySpi.setIpFinder(discoveryMulticastIpFinder);

       cfg.setDiscoverySpi(discoverySpi); 


     Ignite ignite = Ignition.getOrStart(cfg);

 IgniteCache<Integer, Person> cache = ignite.getOrCreateCache("person");    

        // Code to call cache put or get here
       // putCache(cache);
        //getCache(cache);
        System.out.println("All Available Cache on server : "+ignite.cacheNames());

但是在运行上，我得到的错误是：

Caused by: class org.apache.ignite.spi.IgniteSpiException: Local node and remote node have different version numbers
 (node will not join, Ignite does not support rolling updates, so versions must be exactly the same)
 [locBuildVer=2.7.5, rmtBuildVer=2.8.0,

请帮我解决这个问题。另外，我上面提到的代码是连接到用作应用程序缓存的 ignite 数据库的正确方法吗？

Answer 1

错误消息告诉所有需要的：

Caused by: class org.apache.ignite.spi.IgniteSpiException: 本地节点和远程节点版本号不同（节点不会加入，Ignite不支持滚动更新，所以版本必须完全一致） [locBuildVer=2.7.5, rmtBuildVer=2.8.0,

Ignite 仅支持来自相同节点的集群，因此，您应该将本地节点升级到 2.8.0 或将远程节点降级到 2.7.5。
