> After upgrading from IOP 4.2 to HDP 2.6 with Ambari 2.5.2, there are two metrics widget don't show the right results.
> Namenode RPC and Namenode Connection Load graph don't show any data.  This might be caused by different implementation to fetch metrics data for those two graphs in IOP.  Check if there is a way to bridge the gap by updating widget information or document this and ask user to remove the widget.
