> 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
