> Option to let Balancer prefer top used nodes in each iteration

> Normally the most important purpose for HDFS balancer is to reduce the top
> used node to prevent datanode usage from being too high.
> Currently, balancer almost randomly picks nodes as sources regardless of
> usage, which makes it slow to bring down the top used datanodes in the
> cluster, when there are less underutilized nodes in the cluster (consider
> expansion).
> We can add an option to prefer top used nodes first in each iteration, as
> suggested in HDFS-14894 .
