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

configed the rack info of the cluster.
Also, it is convenient to sort the live datanodes table on the column of rack

configed the rack info of the cluster. This can solve easily, just add it in
the dfshealth.jsp, and also for the convenient of sort the live datanode table
on the column of rack, we can just add it in the JspHelper.java.
