我创建了一个在开发集群上运行的actor服务.ASP.NET应用程序(通过IIS单独托管)连接到群集并使用actor.这很好用.

但是,当我将所有内容部署到生产环境时,ASP.NET应用程序无法连接到具有以下异常的群集.群集是内部托管的(Windows 2012 R2).

The type initializer for 'Microsoft.ServiceFabric.Services.ServiceTrace' threw an exception.

根据Service Fabric文档(https://azure.microsoft.com/en-us/documentation/articles/service-fabric-reliable-actors-introduction/),以这种方式创建一个actor代理:

ActorId actorId = ActorId.NewId();

IMyActor myActor = ActorProxy.Create<IMyActor>(actorId, new Uri("fabric:/MyApp/MyActorService"));

await myActor.DoWorkAsync();

好的,这可以工作并连接到我的本地群集.但我无法弄清楚如何创建远程集群的代理？(我有一个三节点集群,IP为10.0.10.10,10.0.11.10,10.0.12.10.)

我还尝试使用ServicePartitionResolver,这里有解释:https://azure.microsoft.com/en-us/documentation/articles/service-fabric-reliable-services-communication/,但没有成功.

我们通过快照为 Cassandra 生产环境设置了备份/恢复程序。快照文件、架构和令牌环信息复制到 S3。

生产集群是一个 3 节点集群，复制因子为 3。

为了开发和测试，我想将生产中的快照恢复到单独的集群中。为了节省资金并方便维护，最好只从一个生产节点恢复快照。由于我们在 3 节点集群中使用复制因子 3，因此每个快照都应包含所有行。一致性对于我们的用例来说也不重要。

是否可以（以及如何）仅恢复单个快照？
