Tim Armstrong created IMPALA-7648:
-------------------------------------
Summary: 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
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
