Akira AJISAKA updated HADOOP-9913:
----------------------------------
Description:
In o.a.h.ipc.metrics.RpcMetrics.java, metrics are declared as follows:
{code}
@Metric("Queue time") MutableRate rpcQueueTime;
@Metric("Processsing time") MutableRate rpcProcessingTime;
{code}
Since some users may confuse which unit (sec or msec) is correct, they should
be documented.
