Hi @Robin Dong, there is a slight dependency to your overall cluster layout.
If e.g. this node is you single Master node of your cluster, then you have to shutdown your cluster first ( Ambari => Stop all services), but if e.g. this node is one of your workers you most probably are fine by putting that particular node in "Maintenance mode", then perform your maintenance work, start it up again and finally disable "Maintenance mode".
