Any Scala SDK or interface for AWS?

Question

Does anyone know of a Scala SDK for Amazon Web Services? I am particularly interested in the EMR jobs.

Take a look at AWScala (it's a simple wrapper on top of AWS SDK for Java):

[UPDATE from 04/07/2015]: Another very promising library from @dwhjames:

this looks impressive. Thanks @Alex – CruncherBigData Dec 27 '13 at 18:19
A bit of a drawback is that AWScala draws in all of `aws-java-sdk` (30 MB lib), even if you only need, say, Amazon S3 and `aws-java-sdk-s3` dependency would suffice (2.7 + 2.4 MB with `aws-java-sdk-core`). – Jonik Dec 19 '15 at 19:49

@jonik seems this has been addressed and you can now only add the S3 dependency if that's all you need – Cpt. Senkfuss Jun 04 '18 at 07:58

You could use the standard Java SDK directly without any problems from Scala, however I'm not aware of any Scala specific SDKs.

Moreover, I don't see why Java SDK may be not suitable for Scala – yegor256 Jun 07 '13 at 05:58

@yegor256 It's badly suitable for Scala because it's blocking by default and its `async` set of classes uses ancient and useless Java `Future` that doesn't have completion callback. – expert Jan 07 '16 at 15:54

Atlassian's aws-scala is quite good.

p.s. Currently the library has basic support for S3, DynamoDB, CloudFormation and SQS

What makes me uneasy about using this one is that the issue tracker is private. So we cannot see the existing bugs or even file bugs. – Johnny Everson Mar 11 '16 at 15:40

It's a bit more complex than others. Could really use some documentation. – Anton Kuzmin Aug 01 '16 at 05:53

You can use just regular AWS Java SDK in scala. For example:

Add the following to build.sbt if you use SBT:

libraryDependencies += "com.amazonaws" % "aws-java-sdk" % "1.12.1"

then:

package example

import com.amazonaws.regions.Regions;
import com.amazonaws.services.s3.AmazonS3;
import com.amazonaws.services.s3.AmazonS3ClientBuilder;
import com.amazonaws.services.s3.model.AmazonS3Exception;
import com.amazonaws.services.s3.model.Bucket;

// for conversions from java collections to scala collections
// e.g. java.util.List to scala List
import scala.jdk.CollectionConverters._

object Hello extends  App {

  // create s3 client
  val s3:AmazonS3  = AmazonS3ClientBuilder
        .standard()
        .withRegion(Regions.AP_SOUTHEAST_2).build();

  // get bucket list
  val buckets:List[Bucket]  = s3.listBuckets().asScala.toList          

  // print bucket names
  buckets.foreach(b => println(b.getName()))
}
