Juan Yu has uploaded a new patch set (#3). 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 network 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.
