Azure Service Fabric: The primary or stateless instance for the partition has invalid address, this means that right address from the replica/instance is not registered in the system.
What should you do when you are using Azure Service Fabric and you receive the following error code when you call a Reliable Service that is Stateful:
Remote Call:
Service
Solution
The problem is from CreateServiceReplicaListeners and is happening because there is no listener set. The only thing that you need to do to be able to make a call over Service Remoting is to set the listener as below.
The primary or stateless instance for the partition has invalid address, this means that right address from the replica/instance is not registered in the system.Sample
Remote Call:
IStatefull smsService = ServiceProxy.Create<IStatefull>(
new Uri("fabric:/ITCamp.SF/Stateful"),new ServicePartitionKey(1));
await smsService.SendSmsAsync(
phoneNumber,
$"{DateTime.Now.ToShortTimeString()} Hello ITCamp!, from '{phoneNumber}'");
Service
internal sealed class Stateful : StatefulService, IStatefull
{
public Stateful(StatefulServiceContext context)
: base(context)
{ }
protected override IEnumerable<ServiceReplicaListener> CreateServiceReplicaListeners()
{
return new ServiceReplicaListener[0];
}
protected override async Task RunAsync(CancellationToken cancellationToken)
{

while (true)

if (!smsToSent.HasValue)

smsToSent.Value.PhoneNumber);
await tx.CommitAsync();

This is out of date. Do you have an example of the next version of the DLLs where there is no method CreateServiceRemotingListener() ??
ReplyDeleteAwesome catch! thanks! note: same trick for stateless too, only that it's ServiceInstanceListener instead of ServiceReplicaListener
ReplyDeleteI really like the way you put the information. Also thanks to JDer to mention the important point for stateless service. Great guidance post and can save lot of time.
ReplyDeleteFor stateless, this does not compile:
ReplyDeleteprotected override IEnumerable CreateServiceInstanceListeners()
{
return new[] { new ServiceReplicaListener(context => this.ServiceInstanceListener(context)) };
//return new ServiceInstanceListener[0];
}
Yes, the code doen't compiles anymore, because at the Build a new version of SDK wa released, that is not backward compatible with RC.
DeleteIf anyone have issues with CreateServiceRemotingListener not being found, it is an extension method and you can get it by adding the following using in your service:
ReplyDeleteusing Microsoft.ServiceFabric.Services.Remoting.Runtime;
Any resolution to this? I can find it either.
DeleteThanks for all the input from you guys and great writeup as well.
ReplyDeleteFor stateless, this works for me:
protected override IEnumerable CreateServiceInstanceListeners()
{
return new[] { new ServiceInstanceListener(context => this.CreateServiceRemotingListener(context)) };
}
Thanks Michael! After hours of frustration, this was exactly what I needed!
