Change subject: IMPALA-13787: Compensate for inaccuracies of EC2 instances in runtime-profile-test ...................................................................... IMPALA-13787: Compensate for inaccuracies of EC2 instances in runtime-profile-test The resolution of the 'MonotonicStopwatch' is less on some machine configurations. On some EC2 instances, this can be 1 to 10 milliseconds. If events are recorded into the event sequence between this 'jiffy', the relation between the timestamps in the runtime-profile-test do not hold, as events will be recorded to occur at the same time. To properly simulate the events, either the test can be adapted to compensate for inaccuracies or provide higher sleep time between events. As this does not pose problems to the consistency of the recorded within the profile JSON, only the sleep timer has been increased for running tests on such machines.
