See Scala packaging for details on Fedora support for the Scala toolchain; briefly, we have version 2.10.3 of Scala in F19, F20, and Rawhide and are currently (late 2013) working to get sbt 0.13.1 in Fedora as well.
There is no official release of Spark that works with Scala 2.10.3 (or SBT 0.13.x), but the upstream Spark project maintains a branch (tracking master pretty closely) that works with Scala 2.10. I believe the current plan from upstream is to officially support Scala 2.10 in the Spark 0.9 timeframe (early 2014).
With some light Fedora-specific patching, we are able to build and run the Scala 2.10 branch of Spark locally in Fedora against our SBT and Scala. Once SBT is available, other things should follow pretty quickly. Detailed dependency information is below.
Spark requires Scala and SBT in order to build. (Note that there is a Maven build option as well, but it requires artifacts that need to be built with SBT.)
The easiest and most up-to-date place to see the dependency list is in the Spark repository itself, but here we will call out some notable dependencies that aren't already in Fedora:
|lift-json||waiting on sbt availability||willb|
|akka||waiting on sbt availability||willb|
|scalaz||preliminary package done||willb||dependency of lift-json; see willb's github for preliminary package. Will be submitted for review once sbt is available|
|metrics||available||gil||Coda Hale's metrics (Java/Maven build).|
