------------------------------------
Summary: Introduce new style enforce to not import
scala.collection.Seq
Key: SPARK-35894
URL: https://issues.apache.org/jira/browse/SPARK-35894
Project: Spark
Issue Type: Improvement
Components: Build
Affects Versions: 3.2.0
Reporter: Jungtaek Lim
Due to the changes on Scala 2.13, importing scala.collection.Seq or
scala.collection.IndexedSeq would bring weird issue.
(It doesn't bring issue on Scala 2.12 so it's high likely we couldn't indicate
the problem till we see complication failure in Scala 2.13.)
Please refer below page to see the details of changes around Seq.
https://docs.scala-lang.org/overviews/core/collections-migration-213.html
It would be nice if we can prevent the case.
