> Update Scala, Java and Python examples of Direct Kafka word count to access the offset ranges using HasOffsetRanges and print it. For example in Scala,
>  
> {code}
> var offsetRanges: Array[OffsetRange] = _
> ...
> directKafkaDStream.foreachRDD { rdd => 
>     offsetRanges = rdd.asInstanceOf[HasOffsetRanges]  
> }
> ...
> transformedDStream.foreachRDD { rdd => 
>     // some operation
>     println("Processed ranges: " + offsetRanges)
> }
> {code}
> See https://spark.apache.org/docs/latest/streaming-kafka-integration.html for more info, and the master source code for more updated information on python.
