      Description

      Currently CapacityScheduler doesn't handle the case well, for example:

      A queue structure:

          root
            |
            a (100)
          /   \
         x     y
        (50)   (50)
      

      And reinitialize using following structure:

           root
           /   \ 
      (50)a     x (50)
          |
          y
         (100)
      

      The actual queue structure after reinitialize is:

           root
          /    \
         a (50) x (50)
        /  \
       x    y
      (50)  (100)
      

      We should forbid admin doing that.
