Fill in the blanks below to complete the following Apache Spark
program which computes the number of occurrences of each word in a file.
For simplicity we assume that words only occur in lowercase, and there
are no punctuations marks.
JavaRDD<String> textFile = sc.textFile("hdfs://...");JavaPairRDD<String, Integer> counts = textFile.____(s->Arrays.asList(s.split(" "))._____()) .mapToPair(word -> new _______).reduceByKey((a,b) -> a + b);
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);
