We should add tests for most or all of the subtasks of IMPALA-4834 that exercise the expected OOM code path. I'll add some bullet points here to track what the coverage is and what's missing.
Aggregations with large var-len string expressionsTop-N with large windowKudu scans: covered by kudu-scan-mem-usage.testNested loop join: covered by single-node-nlj-exhaustive.testMany duplicate keys on build side of hash joinLarge number of NULLS on build side of NAAJ: covered by spilling-naaj-no-deny-reservation.testHDFS table partitioned insert: covered insert-mem-limit.testLarge analytic window can't be spilled- Queries processing large strings (may need multiple tests to cover different places). large_strings.test has some coverage
