> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.0.0
> Reporter: Steve Loughran
> Priority: Minor
>
> When no credentials are found in the list, an {{AmazonClientException}} is
> raised with a message, which may then be retried the S3a retry code. If a
> specific exception were raised, the retry handler would know to skip
> everything here.
