Annotation Type AlphaComponent

@Retention(value=RUNTIME)
@Target(value={TYPE,FIELD,METHOD,PARAMETER,CONSTRUCTOR,LOCAL_VARIABLE,PACKAGE})
public @interface AlphaComponent

A new component of Spark which may have unstable API's. NOTE: If there exists a Scaladoc comment that immediately precedes this annotation, the first line of the comment must be ":: AlphaComponent ::" with no trailing blank line. This is because of the known issue that Scaladoc displays only either the annotation or the comment, whichever comes first.
