无法连接Apache Ignite群集

我按照blog（）中的步骤在AWS中创建了ignite cluster，现在我正在尝试从本地PC使用java客户端进行连接，但连接失败。 不知道为什么我无法连接

错误：-

Exception in thread "main" org.apache.ignite.client.ClientConnectionException: Ignite cluster is unavailable
Caused by: java.net.ConnectException: Connection refused (Connection refused)

谢谢

您指定了以下端口作为Java瘦客户端的端点：

47100..47700

，但是瘦客户端在默认情况下通过端口

10800

工作

将端口更改为正确的端口，并确保它在AWS上打开。

您知道如何将spark连接到ignite客户端吗ignite+spark的所有示例都创建了本地ignite群集
