> 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.
