-------------------------------
Summary: saveAsTextFile() failed to save file to AWS S3
EU-Frankfort
Key: SPARK-13044
URL: https://issues.apache.org/jira/browse/SPARK-13044
Project: Spark
Issue Type: Bug
Affects Versions: 1.4.0
Environment: CentOS
Reporter: Xin Ren
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-s3, but US one can
save to US-s3.
And we 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
