[Spark SQL]: How does Spark HiveThriftServer handle idle sessions ?

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 ?
