I am new to MapR and trying to deep drive into some of the concepts.
Using Central Configuration, how can i update configurations for set of specific nodes. I know this can be done by placing updated configurations in the respective node folders and run pullcentralconfig script.
Lets say if I have 200 nodes cluster, 20 nodes for Dev. If i need to update config in 20 Dev nodes, I need to create folder for each node and place the same config in all 20 folders and run pullcentralconfig script.
Is there any best or simple way to update config in 20 nodes without creating folder for each node ?
