---------------------------------------------
> Add tests for all cases where OOM is expected

> Key: IMPALA-7648
> URL: https://issues.apache.org/jira/browse/IMPALA-7648
> Project: IMPALA
> Issue Type: Test
> Components: Infrastructure
> Reporter: Tim Armstrong
> Assignee: Tim Armstrong
> Priority: Major
> Labels: resource-management
>
> 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 expressions
> * Top-N with large window
> * -Kudu scans- : covered by kudu-scan-mem-usage.test
> * -Nested loop join- : covered by single-node-nlj-exhaustive.test
> * Many duplicate keys on build side of hash join
> * -Large number of NULLS on build side of NAAJ- : covered by
> spilling-naaj-no-deny-reservation.test
> * -HDFS table partitioned insert- : covered insert-mem-limit.test
> * Large analytic window can't be spilled
> * Queries processing large strings (may need multiple tests to cover
> different places). large_strings.test has some coverage
> * Parquet files with large pages
> * Exchange uses a lot of memory
