尝试从本地计算机连接以点燃缓存时出现IgniteSpiException

Question

我有一个应用程序，它使用IgniteDb作为缓存提供程序。它使用发现url如下：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。我已经把代码写成：

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()); 

但在运行错误时，我得到的错误为：

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)

请帮我解决这个问题。此外，我上面提到的代码，这是连接到作为应用程序缓存的点火数据库的正确方式吗

错误消息告诉所需的一切：

由：class org.apache.inlight.spi.IgniteSpi引起异常：本地节点和远程节点的版本号不同(节点不会加入，Ignite不支持滚动更新，因此版本必须完全相同([locBuildVer=2.7.5，rmtBuildVer=2.8.0，

Ignite只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，或者将远程节点降级到2.7.5。
