@yhuai If we do not disable them, the CLI driver will pass these commands

https://github.com/gatorsmile/spark/blob/84aa14a5deda14083520e8e23f83cdb7f5bbb2bc/sql/hive-thriftserver/src/main/scala/org/apache/spark/sql/hive/thriftserver/SparkSQLCLIDriver.scala#L380-L384

https://github.com/apache/spark/pull/13122
Let me know if you have any concern. Thanks!
