             Summary: Wrong Documentation for Java Word Count Example
                 Key: SPARK-19696
                 URL: https://issues.apache.org/jira/browse/SPARK-19696
             Project: Spark
          Issue Type: Bug
          Components: Documentation
    Affects Versions: 2.1.0
            Reporter: gaurav gupta


Java Word Count example of http://spark.apache.org/examples.html page is defined incorrectly 

'''
JavaRDD<String> textFile = sc.textFile("hdfs://...");
JavaRDD<String> words = textFile.flatMap(s -> Arrays.asList(s.split(" ")).iterator())
                            .mapToPair(word -> new Tuple2<>(word, 1))
                            .reduceByKey((a, b) -> a + b);
counts.saveAsTextFile("hdfs://...");
''

It should be 

'''
JavaRDD<String> textFile = sc.textFile("hdfs://...");
JavaPairRDD<String, Integer> counts = textFile.flatMap(s -> Arrays.asList(s.split(" ")).iterator())
                            .mapToPair(word -> new Tuple2<>(word, 1))
                            .reduceByKey((a, b) -> a + b);
counts.saveAsTextFile("hdfs://...");
''''
