Hi,
After updating to grpc 1.1.1 it seems that the semantics around using
NameResolver have changed. Basically in our (working) 1.0.3 NameResolver
implementation we were doing this in start() :
Collection<ServiceInstance> serviceInstances =
provider.getAllInstances(); // provider is a curator.ServiceProvider
List<ResolvedServerInfo> infoGroups = new ArrayList<>();
for (ServiceInstance serviceInstance : serviceInstances) {
infoGroups.add(new ResolvedServerInfo(
InetSocketAddress.createUnresolved(serviceInstance.getAddress(),
serviceInstance.getPort()),
Attributes.EMPTY));
}
listener.onUpdate(Collections.singletonList(infoGroups),
Attributes.EMPTY);
For 1.1.1 we had to slightly change it to match the listener.onUpdate
signature change:
Collection<ServiceInstance> serviceInstances =
provider.getAllInstances();
List<ResolvedServerInfo> serverInfos = new ArrayList<>();
for (ServiceInstance serviceInstance : serviceInstances) {
serverInfos.add(new ResolvedServerInfo(
InetSocketAddress.createUnresolved(serviceInstance.getAddress(),
serviceInstance.getPort())));
}
listener.onUpdate(Collections.singletonList(ResolvedServerInfoGroup.builder().addAll(serverInfos).build()),
Attributes.EMPTY);
However when our client now tries to connect to the server we get an
exception indicating the channel is not active.
io.grpc.StatusRuntimeException: UNAVAILABLE: Channel in TRANSIENT_FAILURE
state
at io.grpc.stub.ClientCalls.toStatusRuntimeException(ClientCalls.java:227)
at io.grpc.stub.ClientCalls.getUnchecked(ClientCalls.java:208)
Any thoughts what could be going on here ?
Thanks,
Jorg
