      Description

      when using Host Selector widget to select one host, like "localhost", in workspace.js code save_host() function

      for(var i=0;i< obj.options.length;i++) {
      if(obj.options[i].selected) {
      if(i!=0)

      { cookie = cookie + "," + obj.options[i].value; }

      else

      { cookie = obj.options[i].value; }

      }
      }
      var myAjax=new Ajax.Request(
      "/hicc/jsp/session.jsp",

      { asynchronous: false, method: 'post', parameters: "hosts="+cookie }

      );
      this code will rise a ajax request to set hosts in session, but the hosts variable in session will be set like ",localhost", a additional comma will be added even there is only one host selected. I think this bug is introduced by above code.

      And this will cause MetricsController.java getSeriesBySessionAttribute() function

      String[] rkeys = (session.getAttribute(skey).toString()).split(",");

      to split this hosts variable to a zero length string, like string "" and string "localhost", using this string "" to get data in HBase which will retrieve no data.
