> I found that the description of the two fields: +{{ProxyOpFailureStandby}}+
> and +{{ProxyOpFailureCommunicate}}+ in the
> [website|https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-common/Metrics.html#RouterRPCMetrics]
> may be misplaced.
> When I reviewed the code to see the meaning of the two fields, I found that
> their descriptions were indeed misplaced.
> _Origin code_：
> {code:java}
> @Metric("Number of operations to fail to reach NN")
> private MutableCounterLong proxyOpFailureStandby;
> @Metric("Number of operations to hit a standby NN")
> private MutableCounterLong proxyOpFailureCommunicate;
> {code}
> _They should be_:
> {code:java}
> @Metric("Number of operations to hit a standby NN")
> private MutableCounterLong proxyOpFailureStandby;
> @Metric("Number of operations to fail to reach NN")
> private MutableCounterLong proxyOpFailureCommunicate;
> {code}
