------------------------------------------

Github user busbey commented on the pull request:

    https://github.com/apache/accumulo/pull/18#issuecomment-62419110
  
    Over here: https://github.com/apache/accumulo/blob/master/server/base/src/main/java/org/apache/accumulo/server/master/balancer/TabletBalancer.java#L95
    
    line ~95 - 177
    
    The code can't be used directly as-is. but the same pattern could be factored out and

    Also worth looking at ACCUMULO-3311
