Marcelo Vanzin commented on SPARK-27681: ---------------------------------------- bq. we don't need to do this until we support Scala 2.13 I guess my question is why do we need to do it? Your explanation above indicates that the {{Seq}} alias in 2.13 will just be a different type. That's fine since 2.12 and 2.13 builds are not binary compatible anyway. I'd understand this change if the {{Seq}} alias was being removed altogether and you'd need an explicit import, but that doesn't seem to be the case. > 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.
