what if I only like to reboot one server in the cluster?

[#1]

the case here is one of the server need to add more NIC card, so it requests a reboot, what is the steps to reboot one server only in the cluster?

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".

thank you so much Gerd,

well, this is one of 6 master nodes, this is not NN or SNN. so what is your suggestion?
