> In the course of finishing SPARK-14650 I found there are still some compile problems and tens of avoidable warnings in 2.12 that can be fixed without, it seems, impacting the 2.11 build. There's enough work that I made a separate JIRA for it here. 
> It generally includes:
> - Selecting Kafka 0.10.1+ for Scala 2.12 and patching over a minor API difference
> - Fixing lots of "eta expansion of zero arg method deprecated" warnings
> - Resolving the SparkContext.sequenceFile implicits compile problem
> - Fixing an odd but valid jetty-server missing dependency in hive-thriftserver
