[giangnd1999]

Description

When I using spark operator with ingresUrlFormat , when I create multiple sparkapplication, it not create enough ingress for all application, eg when i create 8 sparkapplication at same time, it only create 3 or 4 ingress url
I install spark operator using this command: helm install spark-operator -n spark-operator-ingress --set enableWebhook=true --set enableBatchScheduler=true --set ingressUrlFormat="{{$appName}}.sparkui.cluster.vn" ./
Is this a bug of spark operator ? How can i fix it ?
