代码:
【input = sc.textFile(hdfs://localhost:8020/data/input).split("\t")】
有误。
textFile之后的类型是 RDD,RDD无法直接就 split。
或许应该改为:
【input = sc.textFile(hdfs://localhost:8020/data/input).map(lambda line: line.split("\t"))】
请确认是否如此~~
谢谢~
倒数第三行,Dataset API 的优点,
【DataFrame 和 RDD 之间具有互操作性】,
这句话应该改为:
【与 DataFrame 和 RDD 之间具有互操作性】,
凡请知悉~
