Doc Issue : Apache Spark Streaming guide elaborates UpdateStateByKey Operation and goes onto give an example. However for complete code sample it referes to site.SPARK_GITHUB_URL/blob/master/examples/src/main/scala/org/apache
/spark/examples/streaming/StatefulNetworkWordCount.scala). StatefulNetworkWordCount.scala has changed to demonstrate more recent API mapWithState.
This creates confusion in the document.
Till the time more detailed explanation of mapWIthState is added the reference to StatefulNetworkWordCount.scala should be removed.
