luoli updated HDFS-1090:
------------------------

        Fix Version/s: 0.22.0
    Affects Version/s: 0.22.0
          Description: 
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

  was: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. 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.
