How to resize YARN node?

How to resize YARN node?

New Contributor

I have a yarn cluster with small nodes running on ec2. I resized the ec2 instance to have much more cores and memory. I then would like the ResourceManager to recognize the resized node. I have tried different things (decommision/recommission the node, deleting the node then add the role back etc.) but the node is still showing the previous vcore and memory for this node, even though in cloudera manager view the monitor shows the updated cores and memory. I'm new to YARN but how to force YARN to recognize the new instance type?
