What happened:
When I ran:

kubectl autoscale -n my-ns deployment my-workload \
  --min 1 --max 5 --cpu-percent 50 \
  --dry-run=client -o yaml

the generated manifest did not include the namespace field:

metadata:
  name: my-workload

What you expected to happen:

The generated YAML should include the metadata.namespace field to reflect the namespace provided in the command, e.g.:

metadata:
  name: my-workload
  namespace: my-ns

How to reproduce it (as minimally and precisely as possible):

1. Create a namespace:

kubectl create namespace my-ns

2. Create a deployment in that namespace:

kubectl create deployment my-workload --image=nginx -n my-ns

3. Generate an HPA manifest with --dry-run=client:

kubectl autoscale -n my-ns deployment my-workload \
  --min 1 --max 5 --cpu-percent 50 \
  --dry-run=client -o yaml

4. Inspect the output:
   The generated YAML does not include metadata.namespace, even though -n my-ns was explicitly specified.

Anything else we need to know?:
It happened while I was doing my CKA test. The exam environment uses kubectl version 1.33.

Environment:

• Kubernetes client and server versions (use kubectl version): v1.34.1 - v1.34.1+k3s1
• Cloud provider or hardware configuration: Local environment
• OS (e.g: cat /etc/os-release): Ubuntu 24.04.2 LTS
