In org.apache.spark.sql.hive.thriftserver.SparkSQLSessionManager.init(), SparkSQLSessionManager inits “backgroundOperationPool” by creating a ThreadPool directly instead of invoking super.createBackgroundOperationPool().
This results in the idle-session-check-thread in org.apache.hive.service.cli.session.SessionManager not created. So does Spark HiveThriftServer have any mechanism to clean idle sessions, or it is a bug that we should fix ? -- View this message in context: http://apache-spark-developers-list.1001551.n3.nabble.com/Spark-SQL-How-does-Spark-HiveThriftServer-handle-idle-sessions-tp20173.html Sent from the Apache Spark Developers List mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe e-mail: dev-unsubscr...@spark.apache.org
