> Project: Apache Airflow
> Issue Type: Bug
> Components: operators
> Reporter: Xiaodong DENG
> Assignee: Xiaodong DENG
> Priority: Critical
>
> Because upper/lower case was not considered in the extension check,
> S3ToHiveTransfer operator may think a GZIP file with uppercase ext `.GZ` is
> not a GZIP file and raise exception.
