>             Project: Spark
>          Issue Type: Bug
>          Components: Input/Output
>    Affects Versions: 1.4.0
>         Environment: CentOS

> I have two clusters deployed: US and EU-Frankfort with the same configs on AWS. 
> And the application in EU-Frankfort cannot save data to EU-Frankfort-s3, but US one can save to US-s3.
> And I checked and found that EU-Frankfort supports Signature Version 4 only: http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region
> Code I'm using:
> {code:java}
> val s3WriteEndpoint = "s3n://access_key:secret_key@bucket_name/data/12345"
> rdd.saveAsTextFile(s3WriteEndpoint)
> {code}
> So from my issue I guess saveAsTextFile() is using Signature Version 2? How to support Version 4?
> I tried to dig into code
