Amazon ec2 Cassandra Aws实例使用SSTableloader超时

我正在尝试使用sstableloader将SSTable（.db）文件加载到运行在AWS EC2实例上的Cassandra集群中。发生以下错误：

Established connection to initial hosts

我使用“sstableloader-d publicip path\keyspace\table”，它适用于本地主机，但不适用于EC2实例的公共ip地址（我模糊了地址172…*）的实际ip）

可能与EC2防火墙有关，但是端口80的设置在实例上打开（tcping超时）。

您需要打开安全组中的服务器端口。端口80不用于节点间通信。完整列表如下：
