> The decommission always fail when we start decommission multiple nodes on a 
> cluster whose racks is not enough, a cluster with 6 racks to deploy RS-6-3, 
> for example.
> We find that those decommission nodes cover at least a rack, it's actulaly 
> like we are decommission one or more racks. And rack decommission is not well 
> supported currently, especially for cluster whose racks is not enough already.
