For example, > {code:scala} > object Test extends scala.App { > // spark code > } > {code} > Scala will compile {{object Test}} into two Java classes, {{Test}} passed in > by user and {{Test$}} subclassing {{scala.App}}. Currect code checks against > {{Test}} and thus there will be no warn when user's application subclassing > {{scala.App}} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
