>                 URL: https://issues.apache.org/jira/browse/AIRFLOW-4587
>             Project: Apache Airflow
>          Issue Type: Bug
>          Components: aws, contrib, hooks
>    Affects Versions: 1.10.3
>            Reporter: João Ponte
>            Priority: Trivial
>             Fix For: 1.10.4
>
>
> Problem: 
> In the following hook: 
> [https://github.com/apache/airflow/blob/master/airflow/contrib/hooks/aws_athena_hook.py]
> There is a method get_conn() that initialises conn if it's none but every 
> method in the hook uses conn directly, meaning it will be None when it gets 
> used.
> Checking the AWS Athena Operator, you can see that get_conn() is called right 
> after creating the hook to force initialisation. This is confusing and 
> misleading.
>  
> Solution:
> Replace all calls to self.conn with self.get_conn() to ensure initialisation.
