-----------------------------------

             Summary: SparkSession is not closed until JVM exit.[Spark Branch]
                 Key: HIVE-8959
                 URL: https://issues.apache.org/jira/browse/HIVE-8959
             Project: Hive
          Issue Type: Sub-task
          Components: Spark
            Reporter: Chengxiang Li
            Assignee: Chengxiang Li


During unit test, SparkSession is closed by Runtime shutdownHook, which means it's closed
until JVM exist. During unit test suite, each qfile, as a single test case, would reset SessionState,
which lead to a new Sparksession is created for each qfile. As we know that, RemoteSparkClient
is SparkSession specified, so more and more executors is launched during unit test until blocked
by no more resources.
