Marcelo Vanzin commented on SPARK-27681: ---------------------------------------- bq. varargs methods in Scala will change their signature as they are implemented with Seq Again, why is that a problem? That will only happen in the 2.13 version of Spark.There are absolutely no backwards binary compatibility guarantees in that case. The 2.12 build will keep working just like it does today. > Use scala.collection.Seq explicitly instead of scala.Seq alias > -------------------------------------------------------------- > > Key: SPARK-27681 > URL: https://issues.apache.org/jira/browse/SPARK-27681 > Project: Spark > Issue Type: Sub-task > Components: ML, MLlib, Spark Core, SQL, Structured Streaming > Affects Versions: 3.0.0 > Reporter: Sean Owen > Assignee: Sean Owen > Priority: Major > > {{scala.Seq}} is widely used in the code, and is an alias for > {{scala.collection.Seq}} in Scala 2.12. It will become an alias for > {{scala.collection.immutable.Seq}} in Scala 2.13. To avoid API changes, we > should simply explicit import and use {{scala.collection.Seq}}. -- 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
