Kubernetes Submit Queue eeda892240 Merge pull request #46565 from hex108/exit_kubemark
Automatic merge from submit-queue

Let kubemark exit if it fails to start

Fix the bug: If there is sth wrong to run hollow kubelet, kubemark will just hang instead of exiting. 

I came across the problem when I tried to start kubemark with no-root user.
