Akira AJISAKA commented on HADOOP-11242:
----------------------------------------
Looks good to me, +1. I used HADOOP-11242-test.patch to delay putting Call into
callQueue in 10ms to verify the time is recorded and delayed.

Yeah! A red dot, which specifies the elapsed time when the Call got out of
callQueue, is added > 10ms after the span starts.
> Record the time of calling in tracing span of IPC server
