Steve Loughran commented on SPARK-13044:
----------------------------------------
This is HADOOP-13325; jets3t doesn't support v4 APIs.
you will need to move to the s3a client shipping with Hadoop 2.7.x, which does
meet your requirements.
Closing as a WONTFIX as s3n isn't ever going to get this feature; changing the
title to clarify it's s3n. sorry.
> saveAsTextFile() doesn't support s3 Signature Version 4

> Key: SPARK-13044
> URL: https://issues.apache.org/jira/browse/SPARK-13044
> Project: Spark
> Issue Type: Bug
> Components: Input/Output
> Affects Versions: 1.4.0
> Environment: CentOS
> Reporter: Xin Ren
> Labels: aws-s3
>
> 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
