[jira] [Created] (SPARK-11078) Ensure spilling tests are actually spilling

Andrew Or created SPARK-11078:
---------------------------------

             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
