@Leemoonsoo binary package is the same as before, spark/scala-2.11 and
spark/scala-2.10 will be packaged together into
`spark-interpreter-0.8.0-SNAPSHOT.jar` which doesn't contain scala library.
scala library is in the spark distribution. So SparkInterpreter will load the
correct scala version of SparkInterpreter (`SparkScala211Interpreter` or
`SparkScala210Interpreter`) based the scala version in your spark distribution
(depends on SPARK_HOME you set).
