Subject [jira] [Commented] (SPARK-1812) Support cross-building with Scala 2.11
Date Sat, 02 Aug 2014 20:23:11 GMT

Patrick Wendell commented on SPARK-1812:
----------------------------------------

[~avati] can you create sub-tasks for the individual dependency upgrades? Right now you have
a bunch of different PR's that are all sharing the same JIRA title... our development workflow
assumes there is a 1<->1 relationship between JIRA's and patches.

> Since Scala 2.10/2.11 are source compatible, we should be able to cross build for both
versions. From what I understand there are basically three things we need to figure out:
> 1. Have a two versions of our dependency graph, one that uses 2.11 dependencies and the
other that uses 2.10 dependencies.
> 2. Figure out how to publish different poms for 2.10 and 2.11.
> I think (1) can be accomplished by having a scala 2.11 profile. (2) isn't really well
supported by Maven since published pom's aren't generated dynamically. But we can probably
script around it to make it work. I've done some initial sanity checks with a simple build
here:
