Change subject: IMPALA-14651: Fix flaky test_loaded_tables_metric due to report delay ...................................................................... IMPALA-14651: Fix flaky test_loaded_tables_metric due to report delay test_loaded_tables_metric() added in IMPALA-13863 was failing intermittently because it didn't account for the random delay in ImpaladTableUsageTracker's table usage reporting. The tracker sleeps for [0.5, 1.5) * REPORT_INTERVAL_MS (5-15s) before sending usage reports to catalogd, after which the TTL countdown begins. The test was waiting for timeout * 2, but the actual max time is: - Report delay: up to 15s (1.5 * 10s REPORT_INTERVAL_MS) - Invalidation TTL: timeout - Metric update buffer: ~5s Changed the wait timeout from (timeout * 2) to (timeout + 20) to properly account for the maximum report delay plus TTL.
