Do I Need to Shut Down a Master Node Before Upgrading It?

Question:

Do I need to shut down a Master node before upgrading it in an MRS cluster?

Answer:

As users' increasing services lead to Core node scale-out and high CPU usage, Master node specifications cannot meet user requirements and need to be scaled up.

The Master node automatically shuts down during specifications upgrade, and automatically starts after the upgrade is complete. No manual intervention is required.
