Hi
x.split returns an array. So, after first map, you will get RDD of arrays. What
is your expected outcome of 2nd map?

Thank you sir.
This is what I get
scala> textFile.map(x=> x.split(","))res52: org.apache.spark.rdd.RDD[
Array[String]] = MapPartitionsRDD[27] at map at <console>:27
How can I work on individual columns. I understand they are strings
scala> textFile.map(x=> x.split(",")).map(x => (x.getString(0)) |
)<console>:27: error: value getString is not a member of Array[String]
textFile.map(x=> x.split(",")).map(x => (x.getString(0))
regards

Basic error, you get back an RDD on transformations like
map.sc.textFile("filename").map(x => x.split(",")

Hi,
I have a text file as below that I read in
74,20160905-133143,98. 1121806912882759414875,20160905-133143,49.

val textFile = sc.textFile("/tmp/mytextfile. txt")
Now I want to split the rows separated by ","
scala> textFile.map(x=>x.toString). split(",")<console>:27: error: value split
is not a member of org.apache.spark.rdd.RDD[ String]
textFile.map(x=>x.toString). split(",")
However, the above throws error?
Any ideas what is wrong or how I can do this if I can avoid converting it to
String?
Thanking
