## What changes were proposed in this pull request? Many suites currently leak Spark sessions (sometimes with stopped SparkContexts) via the thread-local active Spark session and default Spark session. We should attempt to clean these up and detect when this happens to improve the reproducibility of tests. ## How was this patch tested? Existing tests Author: Eric Liang <[email protected]> Closes apache#21058 from ericl/clear-session.
