Hi @goiri,
The build infra seems to have some problem.
logfile links for this build seem to point to empty pages.
https://github.com/apache/hadoop/pull/5730#issuecomment-1590242662
the compile logfile for the second to last build has a cmake program error.

I just removed an extra space since the last clean build. it shouldn't cause
these errors.
> Add rpcCallSuccesses and OverallRpcProcessingTime to RpcMetrics for Namenode

> Key: HDFS-17042
> URL: https://issues.apache.org/jira/browse/HDFS-17042
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: hdfs
> Affects Versions: 3.4.0, 3.3.9
> Reporter: Xing Lin
> Assignee: Xing Lin
> Priority: Major
> Labels: pull-request-available
>
> We'd like to add two new types of metrics to the existing NN
> RpcMetrics/RpcDetailedMetrics. These two metrics can then be used as part of
> SLA/SLO for the HDFS service.
> * {_}RpcCallSuccesses{_}: it measures the number of RPC requests where they
> are successfully processed by a NN (e.g., with a response with an RpcStatus
> {_}RpcStatusProto.SUCCESS){_}{_}.{_} Then, together with {_}RpcQueueNumOps
> ({_}which refers the total number of RPC requests{_}){_}, we can derive the
> RpcErrorRate for our NN, as (RpcQueueNumOps - RpcCallSuccesses) /
> RpcQueueNumOps.
> * OverallRpcProcessingTime for each RPC method: this metric measures the
> overall RPC processing time for each RPC method at the NN. It covers the time
> from when a request arrives at the NN to when a response is sent back. We are
> already emitting processingTime for each RPC method today in
> RpcDetailedMetrics. We want to extend it to emit overallRpcProcessingTime for
> each RPC method, which includes enqueueTime, queueTime, processingTime,
> responseTime, and handlerTime.
