-----------------------------------
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.
