----------------------------------

             Summary: Do not use Time#now to calculate the rpc queue time 
duration
                 Key: HADOOP-15768
                 URL: https://issues.apache.org/jira/browse/HADOOP-15768
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 3.1.1
            Reporter: Yiqun Lin
            Assignee: Ryan Wu


For the rpc queue time calculation, we are using a not-recommended way: Using 
{{Time#now}} to calculate for this.
{code}
        // Invoke the protocol method
        long startTime = Time.now();
        int qTime = (int) (startTime-receivedTime);
....
server.updateMetrics(detailedMetricsName, qTime, processingTime, false);
{code} 

We should use {{Time#monotonicNow()}} instead. This JIRA will fix these across 
RpcEngine impl classes.
