I have a small cluster with 2 nodes. It's overloaded, and the only resource I have is a "half" node (with half of RAM). I added it to the cluster, hoping that it will help at least a bit. It ends up with 10% more data than the other 2 nodes relocated to it, and as a result, the whole cluster slowed down. Any way I can specify percentage of data each node should hold? Something like, each of the 2 original nodes will hold 40% of data, while the "half" node will hold 20%.
