> A novice starting out with RSGroupBasedLoadBalancer will want to enable it 
> and, before assigning tables to groups, may want to create some test tables. 
> Currently that does not work when creating a table by cloning a snapshot, in 
> a surprising way. All regions of the table fail to open yet it is moved into 
> ENABLED state. The client hangs indefinitely.
