Hi Sukant, Regarding the first point: when building spark during my daily work, I always use Scala 2.11 and have only run into build problems once. Assuming a working build I have never had any issues with the resulting artifacts.
More generally however, I would advise you to go with Scala 2.11 under all circumstances. Scala 2.10 has reached end-of-life and, from what I make out of your question, you have the opportunity to switch to a newer technology, so why stay with legacy? Furthermore, Scala 2.12 will be coming out early next year, so I reckon that Spark will switch to Scala 2.11 by default pretty soon*. regards, --Jakob *I'm myself pretty new to the Spark community so please don't take my words on it as gospel On 11 November 2015 at 15:25, Ted Yu <yuzhih...@gmail.com> wrote: > For #1, the published jars are usable. > However, you should build from source for your specific combination of > profiles. > > Cheers > > On Wed, Nov 11, 2015 at 3:22 PM, shajra-cogscale < > sha...@cognitivescale.com> wrote: > >> Hi, >> >> My company isn't using Spark in production yet, but we are using a bit of >> Scala.
