You need a "catch all" here:
```
scala> class MyListener extends org.apache.spark.scheduler.SparkListener {
| override def onOtherEvent(event:
org.apache.spark.scheduler.SparkListenerEvent): Unit = event match {
| case _: org.apache.spark.scheduler.SparkListenerTaskStart => ()
| }
| }
defined class MyListener
scala> sc.addSparkListener(new MyListener())
scala> spark.range(1000).write.saveAsTable("test")
17/04/19 10:39:01 ERROR LiveListenerBus: Listener MyListener threw an
exception
scala.MatchError: SparkListenerSQLExecutionStart(0,saveAsTable at
<console>:27,org.apache.spark.sql.DataFrameWriter.saveAsTable(DataFrameWriter.scala:354)
```
