PJ Fanning edited comment on SPARK-27683 at 5/12/19 3:01 PM: ------------------------------------------------------------- [~srowen] would it be possible to use the scala-collection-compat lib? It has a type alias `IterableOnce` that maps to `TraversableOnce` in the scala 2.11 and 2.12 versions of the lib but to the core IterableOnce in 2.13. [https://github.com/scala/scala-collection-compat/blob/master/compat/src/main/scala-2.11_2.12/scala/collection/compat/PackageShared.scala#L156] [https://github.com/scala/scala-collection-compat/blob/master/compat/src/main/scala-2.13/scala/collection/compat/package.scala#L22] The akka team created equivalent type aliases to avoid the dependency on scala-collection-compat and this approach could be used to add additional type aliases that suit Spark's requirements. was (Author: pj.fanning): [~srowen] would it be possible to use the scala-collection-compat lib?

We > should use {{IterableOnce}} instead. This one is a bigger change as there are > more API methods with the existing signature. -- 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
