Ignite 点火缓存重新连接问题（缓存已停止）,ignite,Ignite,目前我们正在使用Ignite2.1和SpringDataIgnite存储库。我有一个服务器节点和一个客户端节点，其中有一个缓存“TestCache”。当客户端连接到服务器，并且服务器节点关闭时，它将断开连接。当服务器节点重新启动时，客户端节点将重新连接 但是，当连接回时，缓存“TestCache”不再可访问，出现以下异常： java.lang.IllegalStateException: class org.apache.ignite.internal.processors.cache.Cach

目前我们正在使用Ignite2.1和SpringDataIgnite存储库。我有一个服务器节点和一个客户端节点，其中有一个缓存“TestCache”。当客户端连接到服务器，并且服务器节点关闭时，它将断开连接。当服务器节点重新启动时，客户端节点将重新连接

但是，当连接回时，缓存“TestCache”不再可访问，出现以下异常：

已尝试以下方法，但似乎无法连接回缓存。对以下问题有什么想法

ig.events().localListen(new IgnitePredicate<Event>() {
        @Override public boolean apply(Event event) {
            switch (event.type()) {
                case EventType.EVT_CLIENT_NODE_RECONNECTED:
                    logger.info("Ignite Client reconnected!");
                    Runnable task = () -> {
                        ig.getOrCreateCache(spaCacheName);
                        logger.info("getOrCreateCache after reconnected");
                    };

                    Thread thread = new Thread(task);
                    thread.start();
            }
            return true;
        }
    }, EventType.EVT_CLIENT_NODE_DISCONNECTED, EventType.EVT_CLIENT_NODE_RECONNECTED);

ig.events（）.localListen（新的IgnitePredicate（））{
@覆盖公共布尔应用（事件）{
开关（event.type（））{
案例EventType.EVT\u客户端\u节点\u已重新连接：
info（“Ignite客户端已重新连接！”）；
可运行任务=（）->{
ig.getOrCreateCache（spaCacheName）；
logger.info（“重新连接后getOrCreateCache”）；
};
线程线程=新线程（任务）；
thread.start（）；
}
返回true；
}
}，EventType.EVT\u客户端节点已断开连接，EventType.EVT\u客户端节点已重新连接）；
提前谢谢~

关于这个问题，我看到了一些信息：

是的，您正确地找到了与此问题相关的问题：

重启后，服务器节点（显然）没有任何关于在停止之前启动的缓存的信息。同时，如果客户端与EVT_client_NODE_RECONNECTED事件重新连接，它不会再次创建缓存，因为它认为它已重新连接到已创建此缓存的同一集群

作为一种解决方法，您可以重新启动客户端节点，它将在正常重新启动后再次创建缓存。

此外，在服务器节点重新启动期间，仍然面临以下JIRA中提到的问题（）。这个问题应该已经解决了。重新连接或断开连接后，可以在代码中重新启动吗？我们计划投入生产，但如果我需要手动重启，这看起来不太适合投入生产。我认为在生产中，您将拥有多个服务器节点，因此您永远不会遇到此异常。另外，是的，可以从代码中重新启动节点，检查点火开关。stop（）和start（）。我们从2个节点开始，所以这两个节点可能同时关闭。我可以试着停下来，看看情况如何。我想我会监听重新连接事件，然后停止点火，然后启动点火。谢谢我正在使用SpringDataIgnite存储库。将ignite Spring Bean替换为新启动的Spring Bean似乎不是那么简单。@cheng您找到解决此问题的好方法了吗？我在GKE上使用可抢占机器，所以缓存节点被重新启动，我得到的缓存被停止错误。
