Load balancing using 'nodetool move'

Hello,

I initially had two node cluster and now I joined another node by keeping intial_token property blank and auto_bootstrap: True. So it took one of the node and shared its half of the load. Now when I run Nodetool ring I get ownership as 25%,25% and 50% which is correct but I wish to make it 33%,33% and 33%, for that I simply used: nodetool -h<node1>  move <newtoken1>

But it gives following error:

Exception in thread "main" java.lang.UnsupportedOperationException: data is currently moving to this node; unable to leave the ring

Kindly note that node1 has initial token, node 2 and node3 doesn't have any intial_token and joined using bootstrapping. Kindly help thanks.

Check nodetool ring to see what state the nodes are in, they all need to be UP.
