-----------------------------------
Summary: 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 Ziemiński
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
