Eric Liang created SPARK-23971:
----------------------------------
Summary: Should not leak Spark sessions across test suites
Key: SPARK-23971
URL: https://issues.apache.org/jira/browse/SPARK-23971
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.4.0
Reporter: Eric Liang
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.
