title: How I dynamically upgrade worker's cpu/ram/disk in dataproc?
body: <p>I created a cluster by default setting(4 vCPUs, 15GB Ram) in google dataproc.
  After working several pig jobs, the cluster had 2-3 unhealthy node.
  So I upgraded the worker VM's vCPUs(4 to 8 vCPUs), Ram(15GB to 30GB) and Disk.
  But in the Hadoop Web interface showed the hardware of worker node didn't change, it still showed the original mounts of vCPU/Ram/Disk.</p>
  
  <p>How can I dynamically upgrade worker's cpu/ram/disk in dataproc?</p>
  
  <p>Thanks.  </p>
