As Spark 2 is not a breaking news anymore, it's time to make reference apps working with it.
I can see at least the following things to do:

Use SparkSession instead of SQLContext
Use Dataset API
Update JavaDStream.foreachRDD() invocations to new contract (returns nothing)
Update JavaPairDStream.updateStateByKey() to new contract (uses Spark implementation of Optional)

I can handle Java part.
The question: do we still need to maintain Java 6 compatible code? Can we exclude support for this outdated Java version?
