Sean Owen commented on SPARK-14222: ----------------------------------- Probably. The limiting factor is often run-time compatibility with whatever version Hadoop will put in the classpath. However I have been using Jackson 2.8.x + Spark 2 + Hadoop 2.6 for a while without issue. > Cross-publish jackson-module-scala for Scala 2.12 > ------------------------------------------------- > > Key: SPARK-14222 > URL: https://issues.apache.org/jira/browse/SPARK-14222 > Project: Spark > Issue Type: Sub-task > Components: Build > Reporter: Josh Rosen > Assignee: Josh Rosen > > In order to build Spark against Scala 2.12, we need to either remove our > jackson-module-scala dependency or cross-publish Jackson for Scala 2.12. > Personally, I'd prefer to remove it because I don't think we make extensive > use of it and because I'm not a huge fan of the implicit mapping between case > classes and JSON wire formats (the extra verbosity required by other > approaches is a feature, IMO, rather than a bug because it makes it much > harder to accidentally break wire compatibility). -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
