Akka.NET Cluster Sharding Example
This project is a worked example of the Akka.Cluster.Sharding module documentation.
Prerequisites
.NET Command Line Tools (1.0.0-preview2-003121)
How To Run
dotnet restore
cd src
For single seed node:
seed=yes dotnet run
For unlimited follower node in a different console:
dotnet run
Expected Behaviour
After the follower node connects to the seed, one of the nodes should start a
single instance of MyActor which should print Actor Instantiated to the console
once across the entire cluster (declaring a single instance of the actor is now
active in the cluster), followed by Received type: String (once for each connected node)
describing that a message was received buy the actor.
The Problem!
After running both the seed and the follower the cluster fails to start an instance
of MyActor and logs a warning:
[WARNING][27/09/2016 14:13:20][Thread 0020][[akka://mysystem/user/sharding/my-actor#674959404]] Trying to register to coordinator at [], but no acknowledgement. Total [1] buffered messages.
Additionally, when the follower node connects to the cluster, the seed node will fail to handle messages sent do it with the following error:
[ERROR][27/09/2016 14:13:19][Thread 0009][[akka://mysystem/system/endpointManager/reliableEndpointWriter-akka.tcp%3A%2F%2Fmysystem%40127.0.0.1%3A59088-1/endpointWriter#1562219685]] Dropping message [Akka.Actor.ActorSelectionMessage] for non-local recipient [[akka.tcp://birchd@127.0.0.1:4053/]] arriving at [akka.tcp://birchd@127.0.0.1:4053] inbound addresses [akka.tcp://mysystem@127.0.0.1:4053]
