Question

我正在尝试填充在其他计算机上的群集上运行的Gridgain缓存。我在调用Gridgain上的方法时获取ClientDisconnectedException，并在调用Cache方法之后获取此方法。

这是我的缓存配置：

// DPH cache
        CacheConfiguration<K,V> DPHCacheCfg = new CacheConfiguration<>(DPH_CACHE);
        DPHCacheCfg.setCacheMode(CacheMode.PARTITIONED); // Default.
        DPHCacheCfg.setIndexedTypes(String.class, DPH.class);
        DPHCacheCfg.setOffHeapMaxMemory(10 * 1024L * 1024L * 1024L);
        DPHCacheCfg.setMemoryMode(CacheMemoryMode.ONHEAP_TIERED);
        FifoEvictionPolicy evctPolicy = new FifoEvictionPolicy();
        DPHCacheCfg.setEvictionPolicy(evctPolicy);

她是如何将数据放入缓存中的：

DPHCache.put（K，V）;其中V是某个对象。在一定数量的看跌期权之后，我有以下例外情况。

这通常在所有服务器节点停止时发生。您应该检查他们的日志以了解究竟发生了什么。

另请注意，当至少一台服务器恢复时，客户端将自动重新连接。 IgniteClientDisconnectedException具有reconnectFuture()方法，该方法返回将在重新连接发生时完成的未来，因此您可以阻止客户端，直到群集正常运行。

class org.apache.ignite.IgniteClientDisconnectedException
