---------------------------------
Summary: Ensure spilling tests are actually spilling
Key: SPARK-11078
URL: https://issues.apache.org/jira/browse/SPARK-11078
Project: Spark
Issue Type: Sub-task
Components: Spark Core, Tests
Reporter: Andrew Or
The new unified memory management model in SPARK-10983 uncovered many brittle
tests that rely on arbitrary thresholds to detect spilling. Some tests don't
even assert that spilling did occur.
We should go through all the places where we test spilling behavior and correct
the tests, a subset of which are definitely incorrect. Potential suspects:
- UnsafeShuffleSuite
- ExternalAppendOnlyMapSuite
- ExternalSorterSuite
- SQLQuerySuite
