> Looks ML events are not JSON serializable. We can make it serialisable like:
> {code}
> @DeveloperApi
> case class SparkListenerSQLExecutionEnd(executionId: Long, time: Long)
>   extends SparkListenerEvent {
>   // The name of the execution, e.g. `df.collect` will trigger a SQL execution with name "collect".
>   @JsonIgnore private[sql] var executionName: Option[String] = None
>   // The following 3 fields are only accessed when `executionName` is defined.
>   // The duration of the SQL execution, in nanoseconds.
>   @JsonIgnore private[sql] var duration: Long = 0L
>   // The `QueryExecution` instance that represents the SQL execution
>   @JsonIgnore private[sql] var qe: QueryExecution = null
>   // The exception object that caused this execution to fail. None if the execution doesn't fail.
>   @JsonIgnore private[sql] var executionFailure: Option[Exception] = None
> }
> {code}.
