Cannot load parquet data from S3

atomix

Hello,

I am trying to load some parquet file sfrom S3 with the following commands to Vertica 9.1:

ALTER SESSION SET UDPARAMETER FOR awslib aws_id=Y;
ALTER SESSION SET UDPARAMETER FOR awslib aws_secret=X;
ALTER SESSION SET UDPARAMETER FOR awslib aws_region='us-east-1';

TRUNCATE TABLE dev.my_logs;
COPY dev.my_logs
FROM 's3://my_bucket/test/01.parquet'
PARQUET
REJECTMAX 100;

However, I am getting the following error:
[Vertica]VJDBC ERROR: Cannot expand glob pattern due to error: Access Denied

Verified, that the IAM user has no problem accessing the bucket or the file itself with
aws s3 ls s3://my_bucket/test/01.parquet
2019-06-11 12:48:34 153600040 01.parquet

Thanks for any help/recommendations.
