> Set appProtocol on spark-connect service port

> Key: SPARK-56275
> URL: https://issues.apache.org/jira/browse/SPARK-56275
> Project: Spark
> Issue Type: Improvement
> Components: Kubernetes
> Affects Versions: kubernetes-operator-0.9.0
> Reporter: Jiwon Park

> Set appProtocol to "grpc" on the spark-connect port in
> DriverServiceFeatureStep.
> Without appProtocol, service meshes (e.g. Istio, Linkerd) treat gRPC traffic
> as opaque TCP, which prevents L7-aware load balancing and gRPC health
> checking for Spark Connect sessions.
> This change is limited to the spark-connect port because gRPC is unambiguous
> regardless of SSL configuration. Other ports (HTTP-based) are left untouched
> since their protocol depends on spark.ssl.* settings.
