>             Project: HBase
>          Issue Type: Bug
>          Components: Balancer
>    Affects Versions: 1.2.0
>         Environment: CentOS Derivative with a derivative of the 3.18.43 kernel. HBase
on CDH5.9.0 with some patches. HDFS CDH 5.9.0 with no patches.
>            Reporter: Kahlil Oppenheimer

> The balancer does not fully respect the maxMovePercent configuration. 
> Specifically, if the number of regions being moved is less than 600, the balancer currently
allows that number of region moves regardless of what value is set for maxMovePercent.
> This patch fixes that behavior and simplifies the moveCost function as well. In addition,
this patch adds short-circuiting logic to the balancer to terminate early once the maximum
number of moves are reached (and assuming the new plan has enough of a cost improvement).
