Can I Change MRS Cluster Nodes on the MRS Console?

You cannot change MRS cluster nodes on the MRS console. You are also advised not to change MRS cluster nodes on the ECS console. Manually stopping or deleting an ECS, modifying or reinstalling the ECS OS, or modifying ECS specifications for a cluster node on the ECS console will affect the cluster stability.

If an ECS is deleted, the ECS OS is modified or reinstalled, or the ECS specifications are modified on the ECS console, MRS will automatically identify and delete the node. You can log in to the MRS console and restore the deleted node through scale-out. Do not perform operations on the nodes that are being scaled out.
