> Under some scenarios, we use the function of disable/enable HTable. But currently, enable
HTable uses the random-assignment. We hope all the regions show a better distribution, no
matter how many regions and how many regionservers.
> So I suggest to add an option of using round-robin assignment on enable-table.
