If I do managedChannel#shutdownNow, will ongoing StreamObserver(belong to this
channel) do onError? If yes, I think when service is unavailable at old
address/port, I should kill the old connection.
The reason I raise this is, that when SkyWalking backend deployed in k8s,
reboot may mean address/port changes. I want to make sure not channel is closed
permanently. Now I am doing this by `isNetworkError` exception received.
I am doing `isNetworkError` in this way
```
private boolean isNetworkError(Throwable throwable) {
if (throwable instanceof StatusRuntimeException) {
StatusRuntimeException statusRuntimeException =
(StatusRuntimeException)throwable;
return statusEquals(statusRuntimeException.getStatus(),
Status.UNAVAILABLE,
Status.PERMISSION_DENIED,
Status.UNAUTHENTICATED,
Status.RESOURCE_EXHAUSTED,
Status.UNKNOWN
);
}
return false;
}
```
@ejona86 If you have any better suggestion to do so (can't use k8s API to do
service discovery:( , this is not an option in the agent ), please let me know.
