> It is a great feature that hadoop support rack-aware, but in the default
> webui of namenode, their is no column in the live datanodes table to show
> what rack the datanode belongs to. This is not convenient for a cluster which
> has configed the rack info of the cluster.
> Also, it is convenient to sort the live datanodes table on the column of rack
