> For example, if you have an custom query execution listener:
> {code}
> package org.apache.spark.sql
> import org.apache.spark.internal.Logging
> import org.apache.spark.sql.execution.QueryExecution
> import org.apache.spark.sql.util.QueryExecutionListener
> class TestQueryExecutionListener extends QueryExecutionListener with Logging {
>   override def onSuccess(funcName: String, qe: QueryExecution, durationNs: Long): Unit
= {
>     logError("Look at me! I'm 'onSuccess'")
>   }
>   override def onFailure(funcName: String, qe: QueryExecution, exception: Exception):
Unit = { }
> }
> {code}
> and set "spark.sql.queryExecutionListeners  org.apache.spark.sql.TestQueryExecutionListener",
> {code}
> >>> sql("SELECT * FROM range(1)").collect()
> [Row(id=0)]
> {code}
> {code}
> >>> spark.conf.set("spark.sql.execution.arrow.enabled", "true")
> >>> sql("SELECT * FROM range(1)").toPandas()
>    id
> 0   0
> {code}
> Seems other actions like show and etc fine in Scala side too:
> {code}
> >>> sql("SELECT * FROM range(1)").show()

> {code}
> {code}
> scala> sql("SELECT * FROM range(1)").collect()
> 18/04/09 16:58:41 ERROR TestQueryExecutionListener: Look at me! I'm 'onSuccess'
