> URL: https://issues.apache.org/jira/browse/SPARK-21385
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 1.6.2, 2.1.0
> Reporter: honestman
> Priority: Minor
> Labels: easyfix
>
> when set spark.sql.hive.thriftServer.singleSession true, In SparkSQLSessionManager will create new Session for each connection, in the process of create new SqlContext it will create new SparkListener and register into listenerbus, but the listener is not removed when the hive session closed, so this would cause too many listener register in the listenerbus, this may cause dropEvent in listenerbus.
