Juan Yu has uploaded a new patch set (#6). Change subject: IMPALA-2076: Correct execution time tracking for DataStreamSender. ......................................................................
IMPALA-2076: Correct execution time tracking for DataStreamSender. DataStreamSender uses multiple channels (each channel uses one thread) to send data. We want to know the active wall-clock time used by DataStreamSender no matter how many threads are used so ignore receiver waiting time and only count concurrent sending time and batch serialization time. Added a ConcurrentStopWatch class to get concurrent transmit time. If a thread is already running, the following thread won't reset the stop watch. And the stop watch is stopped only after all threads finish their work.
