> If we have a long service process of balancer, like namenode, datanode, we
> can get metrics of balancer, the metrics can tell us the status of balancer,
> the amount of block it has moved,
> We can get or set the balance plan by the balancer webUI. So many things we
> can do if we have a long balancer service process.
> So, shall we start to plan the new Balancer? Hope this feature can enter the
> next release of hadoop.
