[jira] [Created] (SPARK-21385) hive-thriftserver register too many listener in listenerbus

honestman created SPARK-21385:
---------------------------------

             Summary: hive-thriftserver register too many listener in listenerbus
                 Key: SPARK-21385
                 URL: https://issues.apache.org/jira/browse/SPARK-21385
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.1.0, 1.6.2
            Reporter: honestman
            Priority: Minor


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.
