thanks bethesda!
But if we have structure like this
a/b/a.txt
a/c/c.txt
a/d/e/e.txt
then how can we handle this case?

On hdfs I created:
/one/one.txt # contains text "one"
/one/two/two.txt # contains text "two"
Then:
val data = sc.textFile("/one/*")
data.collect
This returned:
Array(one, two)
So the above path designation appears to automatically recurse for you.

Hi,
You can use FileInputformat API of Hadoop and newApiHadoopFile of spark to
get recursion. More on the topic you can refer here

How about using the HDFS API to create a list of all the directories
to read from, and passing them as a comma-joined string to
sc.textFile?
