问题描述

我有多个客户端作为 weblogic 服务器上的嵌入式模式启动，并且独立服务器节点存在于 docker 容器中。 服务器和客户端节点都在同一台机器上。

以下是在客户端打印的例外情况。

我认为如果您执行以下代码可能会发生这种情况：

inputCache = ignite.cache(inputCacheName);
CacheConfiguration configuration = inputCache.getConfiguration(CacheConfiguration.class);
outputCache = ignite.getOrCreateCache(configuration.setName("cache_" + ctx.name()));

例如，您从运行的 Ignite 实例中获取缓存，更改其名称，然后出现一个新的客户端节点。 请检查您是否从未这样做，而是始终创建或至少克隆一个新的CacheConfiguration 。

不幸的是，缓存配置是可变的，我们不检查它们是否没有改变。
