thank you very much. just a quick question - I try to save string in this way but the file is always empty:
    val file = Path ("sample data/ZN_SPARK.OUT").createFile(true)    file.bufferedWriter().write(im.toString())    file.bufferedWriter().flush()    file.bufferedWriter().close()
anything wrong ? thanks, canal

 Convert it to a rdd then save the rdd to a file
val str = "dank memes"sc.parallelize(List(str)).saveAsTextFile("str.txt")

Convert it to a rdd then save the rdd to a file

val str = "dank memes"
sc.parallelize(List(str)).saveAsTextFile("str.txt")
