Guanghao Zhang commented on HBASE-18770:
----------------------------------------
bq. What is the read/write metric?
Now we have two class for metric: MetricsRegionServerWrapperImpl and
MetricsRegionServerSourceImpl. The MetricsRegionServerSource is used to update
metric directly. And the MetricsRegionServerWrapper will get metric from the
HRegionServer. The read/write metric is in MetricsRegionServerWrapper. It sum
all online region's read/write metric to get the RegionServer's read/write
metric. In HBASE-19035, we say miss metric which means these read/write metrics.
bq. Presumption is that the CP does the append work itself so we update
metricsRegionServer.updateAppend.
+1 for metricsRegionServer.updateAppend whether CP bypass or not.
> Remove bypass method in ObserverContext and implement the 'bypass' logic case
> by case
