### Issue description
Hi, trying to configure apisix ingress controller with multiple external url
traffic splitting or failover, not sure if current approach is correct, if
there's other workaround, please correct me, thanks.
Here's two features I am looking at:
- if `bar.com` is down, apisix should point to `foo.com` as failover
- if `bar.com` and `foo.com` are both active, traffic will be splitting to
these two urls.
```apiVersion: apisix.apache.org/v2alpha1
kind: ApisixRoute
metadata:
name: httpserver-route
spec:
http:
- name: rule1
match:
hosts:
- local.httpbin.org
paths:
- /*
backends:
- serviceName: apple-service
servicePort: 80
weight: 100
resolveGranularity: service
- serviceName: banana-service
servicePort: 80
weight: 50
resolveGranularity: service
---
kind: Service
apiVersion: v1
metadata:
name: banana-service
spec:
type: ExternalName
externalName: foo.com
ports:
- name: http
port: 80
protocol: TCP
targetPort: 80
---
kind: Service
apiVersion: v1
metadata:
name: apple-service
spec:
type: ExternalName
externalName: bar.com
ports:
- name: http
port: 80
protocol: TCP
targetPort: 80
```
After applying this file, I get `Warning ResourceSyncAborted 1s (x5 over
3s) ApisixIngress ApisixIngress synced failed, with error: conflict headless
service and backend resolve granularity`, seems backend service could not be
`type: ExternalName`
