------------------------------------
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://...");
''''
