[jira] [Created] (SPARK-29310) TestMemoryManager should implement
getExecutionMemoryUsageForTask()
Josh Rosen created SPARK-29310:
----------------------------------
Summary: TestMemoryManager should implement getExecutionMemoryUsageForTask()
Key: SPARK-29310
URL: https://issues.apache.org/jira/browse/SPARK-29310
Project: Spark
Issue Type: Improvement
Components: Tests
Affects Versions: 3.0.0
Reporter: Josh Rosen
Assignee: Josh Rosen
Spark uses a {{TestMemoryManager}} class to mock out memory manager functionality in tests, allowing test authors to exercise control over certain behaviors (e.g. to simulate OOMs).
Our tests have memory-leak detection to ensure that all allocated memory is cleaned up at the end of each test case; this helps to guard against bugs that could cause production memory leaks.
Unfortunately, however, this leak-detection logic is broken for tests which use {{TestMemoryManager}} because it does not override the {{getExecutionMemoryUsageForTask()}} method which the leak-detection mechanism needs.
