> Key: HADOOP-18364
> URL: https://issues.apache.org/jira/browse/HADOOP-18364
> Project: Hadoop Common
> Issue Type: Bug
> Reporter: Shuyan Zhang
> Priority: Major
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> When an RPC protocol is used, the metric of protocol-related methods should
> be initialized; otherwise, metric information will be incomplete. For
> example, when we call HAServiceProtocol#monitorHealth(), only the metric of
> monitorHealth() are initialized, and the metric of transitionToStandby() are
> still not reported. This incompleteness caused a little trouble for our
> monitoring system.
> The root cause is that the parameter passed by RpcEngine to
> MutableRatesWithAggregation#init(java.lang.Class<?>) is always
> XXXProtocolPB, which is inherited from BlockingInterface and does not
> implement any methods. We should fix this bug.
