> Currently DataNode uses same metrics to measure rpc latency of NameNode, but
> Active and Standby usually have different performance at the same time,
> especially in large cluster. For example, rpc latency of Standby is very long
> when Standby is catching up editlog. We may misunderstand the state of HDFS.
> Using different metrics for Active and standby can help us obtain more
> precise metric data.
