Change subject: IMPALA-7600: bump mem_limit for test_kudu_scan_mem_usage ...................................................................... IMPALA-7600: bump mem_limit for test_kudu_scan_mem_usage The estimate for memory consumption for this scan is 9 columns * 384kb per column = 3.375mb. So if we set the mem_limit to 6.5mb, we should still not get more than one scanner thread, but we can avoid hitting out-of-memory. The issue in the JIRA was queue row batches. With this change, and num_scanner_threads=2, there should be max 12 row batches (10 in the queue, 2 in the scanner threads about to be enqueued) and based on the column stats I'd estimate that each row batch is around 200kb, so this change should provide significantly more headroom.
