ASF GitHub Bot commented on PIO-30: ----------------------------------- Github user dszeto commented on the issue: https://github.com/apache/incubator-predictionio/pull/345 @shimamoto There isn't really a policy right now but we should be on the right path if we eventually add support of different combinations like you said (Spark 2.x + Scala 2.10). What would be your suggestion based on this? > Cross build for different versions of scala and spark > ----------------------------------------------------- > > Key: PIO-30 > URL: https://issues.apache.org/jira/browse/PIO-30 > Project: PredictionIO > Issue Type: Improvement > Reporter: Marcin ZiemiĆski > Assignee: Chan > Fix For: 0.11.0 > > > The present version of Scala is 2.10 and Spark is 1.4, which is quite old. > With Spark 2.0.0 come many performance improvements and features, that people > will definitely like to add to their templates. I am also aware that past > cannot be ignored and simply dumping 1.x might not be an option for other > users. > I propose setting up a crossbuild in sbt to build with scala 2.10 and Spark > 1.6 and a separate one for Scala 2.11 and Spark 2.0. Most of the files will > be consistent between versions including API. The problematic ones will be > divided between additional source directories: src/main/scala-2.10/ and > src/main/scala-2.11/. The dockerized tests should also take the two versions > into consideration -- This message was sent by Atlassian JIRA (v6.3.15#6346)
