… pod name for non-StatefulSet pods (apache#17883) In Kubernetes mode, NetUtils.getHost() was returning the canonical hostname (pod name) for Deployment-based pods like Alert Server, which is not DNS-resolvable by other pods. This caused the API server to fail connecting to the Alert Server with 'UnknownHostException'. The fix: For non-StatefulSet pods (where canonical hostname doesn't match the <pod>.<service>.<ns>.svc.cluster.local pattern), fall back to the pod's IP address which is always routable within the cluster. Closes apache#17883
