[jira] [Created] (SPARK-4893) Use test fixture to reset system properties after individual test runs

Josh Rosen created SPARK-4893:
---------------------------------

             Summary: Use test fixture to reset system properties after individual test runs
                 Key: SPARK-4893
                 URL: https://issues.apache.org/jira/browse/SPARK-4893
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
            Reporter: Josh Rosen
            Assignee: Josh Rosen


Several of our tests call {{System.setProperty}} (or test code which implicitly sets system properties) and don't always reset/clear the modified properties, which can create ordering dependencies between tests and cause [hard-to-diagnose failures|https://github.com/apache/spark/pull/3561#issuecomment-67583605].

I think that we should use a ScalaTest fixture / mixin to automatically snapshot and restore system properties after test runs.
