Tianyi Wang has uploaded a new patch set (#3). Change subject: IMPALA-4987: Fix flaky test test_row_availability.py ......................................................................
IMPALA-4987: Fix flaky test test_row_availability.py This patch keeps test_row_availbility from randomly failing. In this test the time interval between the 'Rows available' timeline event and the previous event in the runtime profile is measured in order to make sure that the rows become available after a specific amount of time. This measurement is not correct since the previous event is that the coordinator finished sending the query fragments to the backends, which means the execution on some backends might have already started. This patch tracks another event "Ready to start" as the beginning of the time interval instead. The coordinator begins to send the query fragments to the backends after this event so the time check should always pass.
