> 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.
