> Add override annotation for handleExtraArgs#AbstractLauncher
> ------------------------------------------------------------
>
> Key: SPARK-39111
> URL: https://issues.apache.org/jira/browse/SPARK-39111
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 2.3.0
> Reporter: qian
> Priority: Minor
>
> An overridden method from an interface or abstract class must be marked with
> {{@Override}} annotation. To accurately determine whether the overriding is
> successful, an {{@Override}} annotation is necessary. Meanwhile, once the
> method signature in the abstract class is changed, the implementation class
> will report a compile-time error immediately.
