-----------------------------------
Assignee: Kengo Seki
> Fix RedshiftToS3Transfer not to fail with ValueError
> ----------------------------------------------------
>
> Key: AIRFLOW-2247
> URL: https://issues.apache.org/jira/browse/AIRFLOW-2247
> Project: Apache Airflow
> Issue Type: Bug
> Components: aws, redshift
> Reporter: Kengo Seki
> Assignee: Kengo Seki
> Priority: Major
>
> I tried to use RedshiftToS3Transfer but it failed with:
> {code}
> /path/to/incubator-airflow/airflow/operators/redshift_to_s3_operator.py in
> execute(self, context)
> 69 self.hook =
> PostgresHook(postgres_conn_id=self.redshift_conn_id)
> 70 self.s3 = S3Hook(aws_conn_id=self.aws_conn_id)
> ---> 71 a_key, s_key = self.s3.get_credentials()
> 72 unload_options = '\n\t\t\t'.join(self.unload_options)
> 73
> ValueError: too many values to unpack
> {code}
> This is occurred by unmatch between the number of variables and return
> values. As AwsHook.get_credentials' docstring says, it returns three values:
> {code}
> def get_credentials(self, region_name=None):
> """Get the underlying `botocore.Credentials` object.
> This contains the attributes: access_key, secret_key and token.
> """
> {code}
