> Currently CapacityScheduler doesn't handle the case well, for example:
> A queue structure:
> {code}
>     root
>       |
>       a (100)
>     /   \
>    x     y
>   (50)   (50)
> {code}
> And reinitialize using following structure:
> {code}
>      root
>      /   \ 
> (50)a     x (50)
>     |
>     y
>    (100)
> {code}
> The actual queue structure after reinitialize is:
> {code}
>      root
>     /    \
>    a (50) x (50)
>   /  \
>  x    y
> (50)  (100)
> {code}
> We should forbid admin doing that.
