Writing to frankfurt s3 bucket - Bad request Error

Question

I am trying to write to frankfurt s3 bucket using spark submit but getting 400 errors. com.amazonaws.services.s3.model.AmazonS3Exception: Status Code: 400, AWS Service: Amazon S3. I have following parameter in my spark submit:

--conf spark.hadoop.fs.s3a.endpoint=s3.eu-central-1.amazonaws.com  --conf spark.executor.extraJavaOptions=-Dcom.amazonaws.services.s3.enableV4=true

Any suggestions will be welcome.
