S3 EMR getting folder list with delimiter

I am trying to get the folders name from EMR. For example:

Prefix key = user/temp/

the bucket has the following objects: 

user/temp/2000/1.txt
user/temp/2001/2.txt
user/temp/2002/3.txt
user/temp/2003/4.txt

So I need to get only: 

2000,2001,2002,2003

I am doing the following: 

val objectRequest = new ListObjectsRequest().withBucketName("com.temp").withPrefix("user/temp/").withDelimiter("/")
val files: ObjectListing = s3Client.listObjects(objectRequest)

I am getting 0 files

without the Delimiter I am getting: 

user/temp/2000/1.txt
user/temp/2001/2.txt
user/temp/2002/3.txt
user/temp/2003/4.txt
Solution

  • I found it in the getCommonPrefix()
