'Upgrade the master node configuration on an existing dataproc cluster
I am studying for the PDE certificate so I am currently taking the Course 6: Preparing for the Google Cloud Professional Data Engineer Exam course in Coursera. For the week4 lab I was supposed to Upgrade the master node configuration on an existing dataproc cluster. To do so, I stopped the cluster, go to VM Instances and change the type of the master VM but when I go back to the cluster configuration no change was made and when submitting a new job with the "new configuration" the time was still the same. Some documentation stated that vertical scaling is not currently possible, but since it was in the course I am not sure.
