Review Comment:
   Rather than using Scala objects, which are awkward in Java, we like to use 
Scala's conversions to get Java objects:
   
   ```java
   import scala.collection.JavaConverters;
   Map<String, String> javaMap = 
JavaConverters.mapAsJavaMapConverter(sessionConf.getAll()).asJava();
   ```
