> In Ambari UI, we show properties like NameNode RPC Time.
> We used to get this metric by querying the NameNode component for "RpcQueueTime_avg_time".
> However, in Hadoop 2, it looks like this property name changed to "RpcQueueTimeAvgTime",
so the Ambari API no longer contains these metrics.  Other properties related to NameNode
RPC may have changed.  We need to update the mapping accordingly.
