Just a heads up, we merged Prashant's work on having the sbt build read all dependencies from Maven. Please report any issues you find on the dev list or on JIRA.
One note here for developers, going forward the sbt build will use the same configuration style as the maven build (-D for options and -P for maven profiles). So this will be a change for developers: sbt/sbt -Dhadoop.version=2.2.0 -Pyarn assembly For now, we'll continue to support the old env-var options with a deprecation warning. - Patrick
