commit 5f58545eff6e9aa1c9db8a89d89309713b38e080 Author: Surya Hebbar <[email protected]> AuthorDate: Mon Feb 24 03:51:32 2025 +0530 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.
