> S3A now has a default list of credential providers to pick up AWS credentials from
> The environment variable provider added in HADOOP-12807 should go before the {{InstanceProfileCredentialsProvider}} one in the list, as it does a simple env var checkup. In contrast  {{InstanceProfileCredentialsProvider}} does an HTTP request *even when not running on EC2*. It may block for up to 2s to await a timeout, and network problems could take longer.
> Checking env vars is a low cost operation that shouldn't have to wait for a network timeout before being picked up.
