Sean Owen created SPARK-27681:
---------------------------------

             Summary: 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


{{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}}.
