Takako Shimamoto commented on PIO-199: -------------------------------------- Since Spark 2.4, Spark has upgraded json4s to 3.5.3. As a result, json4s doesn't depend on scala-lang's scalap; that is, it isn't added dependencies on scala-compiler and scala-reflect as well. https://issues.apache.org/jira/browse/SPARK-23043 [https://github.com/json4s/json4s/pull/180] > Spark 2.4 (Scala 2.11) support > ------------------------------ > > Key: PIO-199 > URL: https://issues.apache.org/jira/browse/PIO-199 > Project: PredictionIO > Issue Type: Improvement > Reporter: Takako Shimamoto > Priority: Major > Time Spent: 10m > Remaining Estimate: 0h > > Though Spark 2.4 has added Scala 2.12 support, it is marked as experimental > on the Spark release notes, so the next version of PIO will only add Spark > 2.4 (Scala 2.11) support. > https://spark.apache.org/releases/spark-release-2-4-0.html -- This message was sent by Atlassian JIRA (v7.6.3#76005)
